Unable to search network drives working remotely.

I have posted this to Working Remotely as well....

I have an associate who can search her mapped drives while she is in the
office with no problems. However, when she works remotely over an SSL VPN
connection, it comes back with no results depsite knowing the file she is
searching for is obviously there.

Searching the C:\ drive while remote works fine.

Any ideas?

Thanks
