[pass] WCBS PASS - closes immediately after successful log on

[WTP]

Hi to everyone at Edugeek. First post, long time lurker - thanks to all for this wonderful resource.

 

I'm having a very frustrating problem with some users of the PASS MIS system.

 

Immediately after a successful log in to PASS it closes. No error messages, no logs, netmon shows nothing special (just closed tcp sessions).

 

The problem is only occuring on Win7 workstations, for whatever reason I am unable to replicate it on XP SP3.

 

Our PASS environment on the server is the following:

PASS Application installed on a W2K8 R2 Standard virtual server

SQL 2008 R2 installed on a W2K8 R2 Standard virtual server

Server does not run to capacity on drive space, processor or memory

 

Our PASS environment on the client is the following:

Windows 7 some clients have SQL Tools 2005 installed, some clients have SQL Tools 2008 installed

XP SP3 all clients on this platform run with SQL Tools 2005 installed

Simple shortcut on desktop to PASS2.exe on PASS application server

 

I originally believed this to be a network issue but now users spread throughout both campuses are experiencing this issue. One that is completely on fibre. The networking issue (if it is this) could be on the server side but as there are 7 other virtuals I would expect to see problems ocurring on other servers, with other applications or something in the event logs. There is nothing that points to a problem.

 

Any help would be much appreciated as this is quickly becoming (has become actually) a business critical issue.

 

Many thanks,

William P

Two quick questions:

 

1. What version of PASS are you on?

2. Have you run ProcMon as well as NetMon?

Hi AngryT -> answers inline below.

 

1. What version of PASS are you on?

2.5.1.6 - I know there's a version update, it doesn't address this issue and I want to resolve it before updating.

2. Have you run ProcMon as well as NetMon?

No, I haven't - that's a good point, hopefully it will show more than pass2.exe closing.

Thanks for your help.

More info. There's no an error that is the Event Viewer->Application log. It's generating an Event ID 1000, faulting ntdll.dll

Faulting an access violation in pass2.exe and crashing.

 

We've done an sfc /scannow and the file is file.

 

If anyone has any thoughts it would appreciated. All answers valued and all leads pursued! :-)

Windows updates, to make sure everything is up to date, post pass install on client.

Does it occur regardless of the version of sql tools installed?
