ORA-01019 error only as an administrator

I'm having a strange problem.

I've installed the Oracle 10g client on a terminal server running Windows Server 2008R2. When I try to connect to Oracle, using, say, Toad, I receive the error "ORA-01019 unable to allocate memory in the user side". But this only happens if I'm logged in as an administrator.

If I connect as a normal user, I can connect without issue. Also -- if a normal user is connected, I can then connect without a problem as an administrator.

Any thoughts?

Solution 1:

Does running the terminal server client in console mode change anything? Try the following command:

%SystemRoot%\system32\mstsc.exe /console
