OK, I'll confess... I just skimmed the code and posted (hastily) the first thing I noticed.

I mistakenly left in that second IF. I didn't look at the perms issue.

Upon closer scrutiny, the following line is also wrong.
copy "@LDRIVE"+"\tyr\vphome\grc.dat" "c:\Documents and Settings\All Users\Application Data\Symantec\Norton AntiVirus Corporate Edition\7.5"

You see, @LDrive expands to \\Server\ so once expanded there would be two hacks after the server name.
