Question : PSEXEC commands no longer working - "Access is denied" error

Experts-

Two days ago, scripted commands like this were working fine:
psexec \\OTHER_WORKSTATION -u mynetwork\administrator -p mypass -d -i "notepad.exe"

Now, I'm getting this error:
Couldn't access OTHER_WORKSTATION:
Access is denied.

What could've changed in the IT world that would not allow this to work anymore?

Thanks

Answer : PSEXEC commands no longer working - "Access is denied" error

Assuming "mynetwork" is the domain........

try using the -u "TARGETPCNAME\administrator"

Can you \\other_workstation\c$ using the mynetwork\administrator "mypass " credentials?
