srvinfo failure

I have a question on the utility “srvinfo”. We use this command extensively to report back information on drive size on all our w2k servers for monitoring. The situation I have is the following and is for 2 indentical servers.
> User is member of admin group on both servers.
> User logs onto server A, runs “srvinfo” on box and receives disk size info.
> User logs onto server B, runs “srvinfo” on box and does not receive disk size info.
> User logs back onto server A, runs srvinfo against server B and disk size info is returned.

What obvious point am I missing here? Group policies are the same on each server. Can’t find any feedback info on technet.

Advice please?
