Roaming profiles again

[Lubomir]

Thanks to Jason Todd mail I realized what was the problem with my 
roaming profiles (you know - all these *.bak , *.000 locally stored 
profiles etc.). But what is the best solution...

1.Background:
Samba 2.0.7 server. Win NT4 (sp6) workstations.Roaming profiles.
10 MB soft, 12 hard server disk quota for every user.

2.The problem (one of them;-):
Many users reach their quota (usually iexplorer cache eats kbit by kbit 
their space) and when they logoff WS is not able to upload the new 
profile on the server.
It happens too often, users complan they didn't used so much space but 
their <homedevice> was full and I am reseting user profiles whole my days.

3.One possible sollution (virtually yet):
Reduce iexplore cache size and force eraseing when exit or just set 
cache path c:\temp (that's the easy part).
But am thinking about some global solution...
Is it possible to manage two user quotas - one for their home space and 
another for their profile? And how to do it?
If anybody has succeed running anything like this or if there are better 
solutions please let me know!
