[NTSysADM] Looking for tool to manage many AD domains at once

[Tom Miller]

At my company, we manage multiple domains.   These are different customers
and have no relationship  to each other.  Does anyone have any suggestions
for a tool that would allow technicians to view (ADUC for example) several
domains at once?  The goal is to save support time by not having to
continuously connect/disconnect to client systems.
