Hello all! I´m having a strange problem on my app using ICS 6, I have noticed that my server service raises an exception "Access violation at address 7C8224B2 in module 'ntdll.dll'" but I didn´t got where the problem is happening, analysing the error logs I realised that this error is being raised when a client tries to connect to the server, but this error is just happening on Windows 2003, on XP is OK and the strange is that has no time to occur, it works fine for the most of the time, but sometimes it starts raising those exceptions and my server sofware crashes.
I have searched on google for this error and I saw a message that was sent to this list that another user had the same problem as me and it was said that the user has changed some lines of code on ICS and solved it This problem is happening on a lot of mine customers using Windows 2003, on WIndows XP it doesn´t happens Any Ideas???? Following is the message that Fraçois wrote about the problem: Thanks!!!
