We never seemed to be able to get quota.ini changes to stick. Ours was abuse of the long file name support. You got a file share on the server supporting the Windows 95 PCs, and a file share on the server (Netware, IIRC?) supporting the Windows 3.1 ones.

Quota for the 95 share was checked when logging on to a 95 box, quota for the 3.1 share checked when logging on to a 3.1 box. However, if you saved a LFN file on the 3.1 share from one of the Win95 PCs, it was somehow to all intents and purposes invisible to the Windows 3.1 computer - and thus not counted by the (client-side!) quota manager.
