System.Runtime.InteropServices.COMException in WebPart

[sekhar mantrala via .NET 247]

I too got the same problem accessing the active directory while trying from a webpart in share point portal server. The sample code is as follows...

DirectoryEntry entry = new DirectoryEntry("GC://corp.microsoft.com");
DirectorySearcher dSearch = new DirectorySearcher(entry);
dSearch.Filter = ("(&(objectClass=user)(SAMAccountName= " + UserAlias + "))");
SearchResultCollection result = dSearch.FindAll(); //////////the error occurs here
dSearch.PropertiesToLoad.Add("samaccountname");
foreach(SearchResult sResultSet in dSearch.FindAll()) ////////the error occurs here

The same code works fine in a seperate web application/windows application.

Can anyone have any idea why this happens and help me in identifying the issue?

Thanks in advance

What is the error and the stack trace? I'm guessing you too are having a
double hop issue, but it is hard to say.
