Well, I saw that you were a network administrator, so I assumed that you were operating some sort of large Windows-based domain. I unfortunately don't have that much experience with Windows networking, I've mostly used Novell for large applications. With Netware, you have login scripts for each user/group that map network drives, run applications, etc. upon login.
I was just saying, instead of using delprof.exe /C:\\<computername>, it might be easier to distribute a batch file to every machine that deletes all local profiles (instead of doing the deleting remotely, omit the /C flag) and add it to the startup items of each computer (HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run) with remote registry?
Idk, just a thought... I'd love to see it work the way you intended in the original batch file, though; it seems like the most efficient, straightforward way to do it.
