File.Exists not working.

[George Lake]

Now this is strange.
I had an app runing on W2K Pro and now that its on XP I cant find a file.

The code that is not working is:
If File.Exists("O:\DTX Import UMAR\AsTester.txt") Then

Where "O:\DTX Import UMAR\AsTester.txt" is a network path.

Any ideas why this is not working?

mmm
It should work then. The application is running under the same user as the
old server.

You can use filemon from www.sysinternals.com to see if it is really trying
to do what you want.

What user? If it is "system", then XP won't let the network IO succeed.
This is one of the security changes from W2K to XP.

It´s a domain user that has admin rights on the target server.

Does the user have the O drive mapped to the correct network share? Also,
can the user browse to that file manually and open it?

yes to both.
what beats me is that the same app runing under the same user works on win2k
Pro and not on XP pro
