\\computername\c$ stopped working when XP was upgraded to SP2

[BIGKernel44]

Prior to the deployment of SP2 all the saved network places on our production
server (running 2003) were all functional, using a \\"computername"\"network
share" format. Now the computers in the test enviroment that were upgraded to
SP2, show up as unavailable. Is there a new format or security setting that
I'm missing?

I forgot to mention, that I already checked the new firewall settings to make
sure that the file sharing was still enabled and that the default share was
C$ and that I had the proper permissions as well.
