Find User Applied To All Network Shares

We currently had a user who had been here longer than anybody. He has
his user account tied to services, shares, etc. So when I disabled
his account, we had stuff crashing all around us. I am currently
trying to hunt down a way to scan all of the shares that reside on the
filer, which is 100's if not 1000's, but have no idea where to begin.
This is obviously way too much to handle manually. I looked at
SysInternals ShareEnum, but that didn't work. Are there any other
ideas out there. Any information would be greatly appreciated.

Thank you in advance,
