My workstation with Windows7 professional is a member of a domain. I have local administator priviledges, and a separate account with standard privileges as every other user in company.
I need to switch between the two accounts while working, but the "Switch user" button is disabled, and there is no "switch user" option after pressing alt+ctrl+del.
I have seen Can 'Switch User' in Windows 7 work with Active Directory? thread, but there is nothing useful apart that it can be done.
I have checked out gpedit.msc and Hide entry points for fast user switching in Local Computer / Administrative Templates / System / Logon is set to Not configured, but I tried both enabled and disbaled without success.
I have checked out services.msc, as I read that fast user switch compatibility service should be enabled and running.
The thing is there is no such service. It is not disabled, or something. There is no such entry on the list.
How to enable this functionality? Can I do it alone, or my Active Directory administrator have to set some options on domain controller? Is it possible in mixed XP / Win7 domain?
P.S.:
I have Polish version of Windwos, so I have translated the names of options and service to english, and I might translate it not exact. The service name in Polish should read Zgodność szybkiego przełączania użytkowników, but there is no such service.

fast user switch compatibilityin services.msc, but I do not know how to make it appear there. – SWilk Mar 30 '11 at 8:21
