We have an Index Server on Win2k Server SP4 indexing about 250.000 docs.
We have written an ASP.NET serch page, setup a new virtual directory, and
set to use .NET framework 2.0.
On the server is installed also .NET framework 1.0, for the rest of the
Intranet.
The search page is setup to impersonate the user running the query
in order to return only the documents that the user have access to.

However most of the times, after a number of seconds (like 30 or more),
we receive the error message "An error occurred while attempting to
impersonate."
(see error details below)
I've looked around for a time, but I couldn't find any helpful info.

Do you have any ideas?

Thanks in advance.
Best Regards,
Leonardo Arena

Incidentally I discovered the cause of the problem.
Index Server had not yet finished to index all documents.
Now that indexing has finished, the error disappeared.

Hi Leonardo

Is there anyway you can share your ASP(x) source code which does the
Search.
If you could also let me know "How to/What to" setupon Index Server
that would be great, I have a similar requirement and dont know how to
do it though.
