strange .net runtime error and the fix

Filed under: computer geek stuff,iis,scom,scripting — Tags: .net, cocreate, profiler, scom — jayntguru @ 4:02 pm

We had done a POC for Foglight by Quest back in March and ended up not purchasing the product because we already had SCOM in place. After the uninstall and ever since, we have had some issues.

errors logged whenever an app pool starts/restarts containing this description

.NET Runtime version 2.0.50727.3603 – Failed to CoCreate profiler.

.net health monitoring would log an app pool start but not log an app pool stop or shutdown

I had the suspicion that this was related to random app pool restarts during the day on one of our webservices

other debuggers would not attach to an app pool and work (like avicode that comes with SCOM)

I looked for how to fix this since March, of course I was too stubborn to call Quest, so that’s my fault. Much googling didn’t resolve much so when I finally did figure this out, I wanted to post what I found. It turns out that debugging is set in an environment variable. Seems like it’s a session variable because it’s set in the parameters of a service, so that way it runs with the service in the user context of the service. This is something I had never run across before so it seemed kinda odd.

In the end we had to remove the reg key “Environment” (and the contents of the key) from the two locations. This key is what sets the debugger to enabled and tells it which debugger to use.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W3SVC]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\IISADMIN]

Once these have been deleted, all you have to do is IISRESET the server and the error is gone and random app pool restarts have ceased. As of this writing I have not tried to reinstall the SCOM AVIcode to the webservice, but I’m certain that it will work now.

SQL query to tell if SQL logins are using Kerberos or NTLM

Filed under: computer geek stuff,iis,scom,scripting — Tags: biztalk, kerberos, ntlm, sql — jayntguru @ 4:49 pm

Not explanation needed here, if you know what you are looking for, this is it.

SELECT s.session_id , c.connect_time , s.login_time , s.login_name , c.protocol_type , c.auth_scheme , s.HOST_NAME , s.program_name FROM sys.dm_exec_sessions s JOIN sys.dm_exec_connections c ON s.session_id = c.session_id

TFS 2008 to TFS 2010 Install notes

Filed under: computer geek stuff,iis — Tags: iis, install, tfs 2008, tfs 2010, upgrade, visual studio — jayntguru @ 1:10 pm

Recently (about 5 minutes ago) I did an upgrade in production of our Team Foundation 2008 server to Team Foundation 2010. I had a dry run that worked well but of course on the real thing I had a couple of issues. Here are some notes.

TFS requires sysadmin on the new SQL server, it wants to create/drop databases like crazy
TFS previous to 2010 required sharepoint to be installed, with 2010 it’s just an option, you can add it later.
To clean up from an earlier install (failed, test run, etc.) you can run this command (see the gotcha at the end!)

C:\Program Files\Microsoft Team Foundation Server 2010\Tools>tfsconfig setup /un
install:all

The steps are

Install TFS 2010
Configure TFS 2010 (this creates databases)
Backup your old TFS databases (all of them)
Restore your old TFS databases to your new sql instance
Run the TFS import command from command line. It should look like this:

C:\Program Files\Microsoft Team Foundation Server 2010\Tools>Tfsconfig import /s
qlinstance:server\instance /collectionName:imported /confirmed

Once you do this, you should be good to go

We had an error when trying to install on production because it kept finding information from the previous one. Apparently the tsconfig /setup uninstall:all doesn’t really uninstall all! There were extended database properties left over that we had to delete manually. Until we did this, we received this error:

TF30046: The instance information does not match.

There are very useful logfiles located in:

C:\ProgramData\Microsoft\Team Foundation\Server Configuration\Logs

In order to get visual studio 2005 to connect to TFS 2010, you have to install in this order:

Visual studio 2005
Tfs plugin for vs 2005
Vs 2005 sp1
Vs 2005 vista compatibility update (run windows update)
Vs 2005 TFS 2010 update
Then you enter the full URL in the server name field: http://tfs2010_server:8080/tfs
If it tells you that you can’t put in the “/” and such, it means you installed in the wrong order.

In order to get visual studio 2008 to connect to TFS 2010, you have to:

Install vs 2008
Install vs 2008 sp1
Install vs 2008 TFS compatibility pack
Enter servername as: http://tfs2010_server:8080/tfs

That’s all I have for now. After all the devs come in and hit this tomorrow I may have some more updates (but I hope not!).

MSMQ MP for SCOM–has issues..

Filed under: annoyances,computer geek stuff,iis,scom — Tags: alert, fail, msmq, scom, system center operations manager — jayntguru @ 2:19 pm

This is just an example of the kind of stuff I find in the MSMQ MP for scom. Is this alert about the SIZE of the messages or the NUMBER of messages?

scom missing performance counters

Filed under: annoyances,computer geek stuff,scom,scripting — Tags: error, scom, system center, upgrade — jayntguru @ 3:02 pm

I recently had to make some changes to my scom test environment server. It’s a single virtual machine with scom, sql, ssrs, the works on it. Despite what one would think, it has performed well with about 30 agents. Recently I added about that many more and it pushed up the ram to the 4gb max that I had given it. When I added more I realized I had used 2008 x32 for the OS (oops) and was not able to see the extra ram. After some research I found that I could do an upgrade from 2008 standard to enterprise, which is what I did. Afterwards, scom wouldn’t run because the SDK service would not start. This is the event log message.

Dashboarding using the SCCM Dashboard solution accelerator example

Filed under: computer geek stuff,iis,scom — Tags: dashboards, sccm, scom, sld, solution accelerator — jayntguru @ 5:07 pm

I will turn this into a more useful blog post when I have a few minutes but for now it is just a collection of links about dashboarding using the System Center Configuration Manager Solution Accelerator. The short story is that this runs on top of Sharepoint 3.0, which is free, meaning you can run this for free. It’s not specific to SCCM so you can dashboard any sql data you want! Cool!

cleaning up the default management pack

Filed under: computer geek stuff,scom — Tags: clean, default mp, management pack, operations manager, scom, system center — jayntguru @ 1:56 pm

SCOM has what I feel is a major bug in that it will allow you to save items (monitors, rules, overrides, etc.) in the default MP. Doing this is bad for a lot of reasons, and not only does SCOM allow you to do this, but it is the default option as well. In my case it turned out that an occasional lack of attention allowed me to do this and then removing MP’s later becomes a huge pain in the rear. Anyway I found this good article on how to clean up the mess.

SCOM: powershell run space failed to start

Filed under: computer geek stuff,scom,scripting — Tags: cannot run powershell, powershell, powershell permissions, run space, scom, script — jayntguru @ 2:07 pm

I have been getting these messages since day 1 and tried various things that didn’t work to resolve.

Below I am pasting an example rule with full text so that if someone is searching they will find it. This is one specific alert, I was having an issue with all non microsoft powershell scripted discoveries. For me this was 99% from the XSNMP SCOM Management Pack. To be clear the MP was not the cause of the problem, only the one that tried to run PS (and not work) the most.
