We have a web application (FW2.0) works fine in Win2003 server environment.Currently we are working to deploy in Win2008 server.
Application throws error like "Service is unavailable" when we start browse the default page.
I found logs as follows:-
IIS logs : There is no error logged, It contains error code 200 0 something
FREB Report: None
HTTPERR : 2010-09-03 13:37:54 ::1%0 53335 ::1%0 80 HTTP/1.1 GET /wv3/ - 1 Connection_Abandoned_By_ReqQueue .Net+2.0+App+Pool
As per HTTPERR, Worker Process (W3wp.exe) gets termination on every page request but unable to find the actual reason behind of worker process termination.
When we debug in code, it get struck at a DLL call (refer below code),
EISRose.dll made using VB6, unfortunately we dont have source code for this DLL but the same dll works fine in Win 2003 (II6) environment.
Now, I want to debug further to know the reason behind Worker Process termination (Connection_Abandoned_By_ReqQueue ).
Please help me on this. Thanks

I guess, the cause could be usage of VB6 Dll but how do i make sure that?. Please let me know the best technics or methods to trace the Worker Prcoess termination (Connection_Abandoned_By_ReqQueue) issue in IIS7 (Win2008).
In addition, there is a Window application which consumes same VB6 Dll and works without any issue in Win2008 environment. so this issue is not related with DLL platform compatibility (32 or 64-bit) in Win 2008. Please let me know your view on this.
