Distributed File Service and Home Folders

Wondering if anyone has run into this before and has an answer.

We have to Servers FileserverA and FileserverB

We run DFS and FRS to automataclly replicate home folders and other shared
data on the drives.

Both are running Windows 2003 Server

All users were setup with home folders on FileserverA.

Users at site FileserverB complained it was too slow to open across the
wireless link.

I moved home folders for those specific users to FileserverB (we also use
folder redirection for my documents to point to home folders)

ALL DATA in home folders were erased automatically!!!! Only very small
amounts of data in some users home folders were still there in the morning
all other data was gone.

Good thing I backup

Any answers on what happened? TIA
