"The Page cannot be displayed" error message on Postback (.net 1.1/Win2000Server/IIS 5.0)
Posted on 2009-04-07
I am maintaining a web application created in .net 1.1 with SQL server 2000 as database.
The website is hosted on Windows 2000 server with IIS 5.0
Till date the site has worked fine without any problems.
Recently it was notified by a client that the site shows "Page cannot be displayed" on click of any button which postbacks to the server on the login page (Login page is displayed correctly).
On further investigation, it came to light that the problem occurs on some machines while using LAN or on some other machines while using wireless for networking (switching to other mode of networking - the page works fine).
I have traced the IIS logs which show HTTP 500 error (Win32 status code 87).
Also, through some trial and error by publishing dummy sites I found out that the problem can be regenerated only if I connect to the database, pull some data and display it on page or store in session. Otherwise the postback works okay.
I have tried configuring session states to both InProc and ServerState without any change.
I am really stumped and am not sure how to proceed with this issue.
Any help or guidance whatsoever would be really appreciated.
Thanks and Regards,
