Deployments Stopped Working

[idontknow]

Hey everyone,

One day, seemingly out of the blue, deployments have stopped working.  As far as I can tell nothing has changed with the admin user's permissions, the share location that hosts the installers being deployed, or Group Policy Objects.  What's more frustrating, is that we have 3 other offices with the same setup and it works great.

When using the Scanning Credentials, we get this error:

"Preliminary checks failed. Task Registering Error. A specified logon session does not exist. It may already have been terminated. (Exception from HRESULT: 0x80070520) Credential: (<domain>\<admin>). ShareCredential: (<domain>\<admin>)."

When using the System Account, we get this error:

Result: Deployment ended: This installation package could not be opened. Verify that the package exists and that you can access it, or contact the application vendor to verify that this is a valid Windows Installer package. Stop(Failure). Credential: (<domain>\<admin>). ShareCredential: (<domain>\<admin>).
Command: msiexec.exe /i "\\path\to\installer.msi" /norestart /qn

Any help would be greatly appreciated.
