Java issues administering HP printers and network equipment

With newer versions of Java and older firmware on HP equipment you may run into Java errors trying to administer the devices through the web interface.  Adding the IP or FDQN to the Java exceptions alone will not work now that High security is the lowest level allowed in the Java control panel. Below are a few fixes I have found.

For an HP ProCurve 2810 switch there needs to be an additional entry in the java control panel in the form of http://x.x.x.x/classes/agent.jar

For an HP 4650 printer I found the java.policy file needs a line to allow the specific port used by the printer interface, this case 161, that is not a normal HTTP/HTTPS port. The file was located in “C:\Program Files (x86)\Java\jre1.8.0_77\lib\security” which could be different based on your JAVA version. A line similar to ‘permission “x.x.x.x:port#”, “connect, accept”;’ will need to be put in the grant section of the file. This is in addition to the http://x.x.x.x in the Java control panel

I hope this helps some other people that run into the same issues. If you have any other fixes I would love to hear them.

QuickBooks 2015/2016 Unrecoverable Error

As any IT person can probably attest to QuickBooks can be a challenge sometimes, it is a widely popular accounting package used by  millions. Most issues arise when it is used in a multi user environment, from simple issues like firewall ports for the DB server, user error like leaving it in single user mode or making their workstation the host, to crazy issues like QB no longer liking the file name and and the only solution is to rename the file. Well this time it turned into tens of hours of frustration and talking to the Office of the President….

Haha, this is only at Intuit we are talking about, not the White House, now back to the problem.  The issue first came up when trying to move from QuickBooks Online to QuickBooks Desktop, every time the export process would fail. I called QBO (QuickBooks Online) support, they were very kind and helpful yet after about an hour of trying still the same result. Their next step was to send me a QB portable file that they created, later that day I got the file, restored the file and QB crashed with an unrecoverable error. Tried a few things with no change, so I decided to try another computer. Well same result once again, another unrecoverable error. Was there a problem with the QB file or was this a bigger issue?  I tried creating a new company file and also opening a sample file, yet again the dreaded unrecoverable error.

Doing some research it appeared to be a .Net related issue, I uninstalled and reinstalled .Net and repaired QB installation. No change, still getting the error.  I installed QB on another 3 computers and they all had the same issue. I uninstalled some programs that were the same between computers and still no change. Not wanting to get too bogged down by this issue and hoping their support could use the QB error logs, I thought I would call QB support. After an hour or so of working with Tier 1 support I asked to be escalated to Tier 2. In all I worked with 4 different people over about 4 days with Tier 2 support, then with a Supervisor. Quickbooks 2016 came out during this and still had the same issue. Ultimately the supervisor told me to reload Windows on all of the machines. I was not happy with this solution so I emailed the VP of Small Business at Intuit who is the head boss over QuickBooks.

Within an hour I got an email that the Office of the President at Intuit would contact me the next business day. The next day I got a call from someone in the local Tucson Intuit location. I rehashed everything that had been gone through and we exchanged some emails. I was then told that they would send someone onsite. Now a week later a person from the local site shows up, and we try many of the things that had been done with Tier 2 support. At this point I have blood running down my forehead from banging my head on the wall at the absurdity of doing the same steps that did not work before over and over again. In talking with this person I glean that while I had sent many of these error reports in that nobody had even looked at any of them. The next step was to have development look at the error logs that have been going into limbo at Intuit somewhere. So now I wait again.

After about 5 days I get a email that they have learned something from the logs and have a fix they would like to attempt, so I arrange to do a remote support session in the morning. It turns out one of the 3rd party programs on my suspect list, IBM iAccess 7.1, might be the culprit even though uninstalling it did not fix the issue. This program adds a bad entry into the machine.config file for .Net off to edit the file at ‘C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\machine.config’ and ‘C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\machine.config’


The iAccess software had added an extra line to the machine.config file which is XML and needs to be properly structured. Once the <DbProviderFactories /> line was removed from the machine.config files we attempt to open Quickbooks and it now works. I tried this on the rest of the machines and they all work now. Lesson learned on this one, delete all files even though .Net was uninstalled. I am grateful that Intuit cared  enough to stick through this and help find the resolution rather than just insist on reloading Windows on all of the machines. I am also investigating this support article from IBM to see if it is related to the problem

Cotap Targeted Spam

Cotap, a company that offers ‘secure’ team messaging for businesses has gone an unethical route and is using targeted SPAM emails to solicit customers. You get an email saying you have been added as a contact for the company, but oddly enough nobody in the organization has used or heard of Cotap’s service.  From searching the internet and seeing posts in the forums at Spiceworks it looks like this service has been doing this for a few months. I would suggest that you mark the emails as spam and add their cotap domain to your spam service blacklist.


Cognos – Formatting Output

In creating reports that are usable by people sometimes there is a necessity to change computer given output in order to make it more reader friendly.  In this accounting package there is limitations on the digits available for job numbers and it is up to a 6 digit field with no special characters so a job number might look like 14248. Unfortunately when creating reports most of the people in the organization would expect the format to be 14-248 instead. To achieve this output I used Cast to break apart the values and add hyphen symbol after the second character.


Basically this takes the 5 digit codes, grabs two characters starting from the first (hence the 1,2) and adds the – symbol followed by grabbing the last there characters starting at item 3 ( 3,3) and then casts this into a varchar that is 6 digits long.

Cognos trials and tribulations – Data Modeling

Having to learn Cognos on the fly has been a challenging yet rewarding experience.  I had done some work with Crystal Reports and Microsoft SSRS in the past and this is a very different beast all together. For one in the environment for my work the Cognos server is hosted by the application provider and Cognos allows a data model to be built, and in this case I do not have direct DB2 SQL access but rather data the way the vendor has modeled it for me. In this case trying to convert from some old reports in a legacy reporting tool for the LOB to a Cognos report proves challenging. Not having direct access to the DB and field names that do not always correlate can make it difficult. Using the ‘Lineage’ tools has helped me to find what I am looking for. To access this, right click on your data object, and choose lineage.


From here you can choose the ‘Technical View’ tab and see what underlying object in the database this object was derived from.


Java 8 WMI query

In the past using a WMI query to filter computers with Java 7 the query looked like

Select * From win32_Directory where (name="c:\\Program Files\\Java\\jre7" or name="c:\\Program Files (x86)\\Java\\jre7")

which fairly quickly returned results.  Now with Java 8 the folder is in a format of c:\Program Files\Java\jre8.0_xx which causes the query to run for about 10 minutes.  In searching for a better way I came up with

Select * From Win32_Product where name like "Java 8%"

which is reasonably fast, since I wanted both Java 7 and 8 my final query was

Select * From Win32_Product where (name like "Java 7%" or name like "Java 8%")


Love and Hate



If you have been working with Windows servers long enough there are a few things that you both love and hate. Two of these things are likely ‘Directory Services Restore Mode’ and ‘System State Restore’.  When things are looking grim and that Active Directory server will not boot properly or the database is corrupted you are hoping that both of these tools are your best friends and cooperate with your efforts to restore the server. If you can successfully boot into ‘Directory Services Restore Mode’ that is step one and you are feeling excited and nervous at the same time. However make sure you keep your fingers crossed, you pray to whatever deity that you believe in, rub a rabbits foot,  or whatever method of generating luck you have and hope that  you have a valid system state backup that is not too old and that it is not corrupt. Once you locate your backup and successfully restore it and then boot into Windows normally you can than check AD and other functions of the server to make sure they are working properly.  If so you know that you can get a good nights sleep that night. If not you will keep looking for a valid system state backup, image backup or other.  Moral of this story is have good backups and be sure to have system state backups as part of your plan. Even better you will also have image based backups both locally and offsite as a last resort.

Yes I lucked out tonight and a system state restore quickly fixed a down server. Time for bed…….

Unable to log into web interface 3Com 4500 Switch

I had a 3Com 4500 switch I was unable to log into the web interface.  Not being familiar with the cli for this device I was at a bit of a disadvantage. Having done a full factory reset I was still unable to access the web interface.  I had a second unit the same steps were performed on which worked just fine. I noticed the firmware was at a 2006 version so I decided the first step would be to do a firmware update.  I was able to get the required files from the HP site as new as 2012.  I downloaded the files, setup my tftp server.  I use which works really well. And wend forward.  I noticed when I did a dir listing of the device it was missing one of the bootrom files. I updated the files, set the boot options and restarted the device. Still unable to log into web interface, after some google fu I found the procedure to reset web access to the device.

Upgrade process:
first get a list of files:
Directory of unit1>flash:/

3 -rw- 1364 Apr 02 2000 00:47:45 3comoscfg.cfg

Next delete the files an clear recycle bin(there is not enough flash space to store both sets, make sure you have backups)
<4500>delete s3p02_01.web
<4500>reset recycle-bin
Clear flash:/3comoscfg.cfg ?[Y/N]:y

Microsoft 70-413 and 70-414 exam updates for R2

Microsoft updated the 70-413 and 70-414 exams on Friday April 4th, ahead of the April 7th time they had told the public. Many people hoping to pass the original exam before the update cutoff failed. I was one of these people.  I got an email address of a MS employee who was very helpful and apologized  for the early test release and gave me the following update guides that show the changes in the test material. I asked to verify I could share these and she said yes.
