Connecting from a TAC Vista Remote Workstation gives error "Ensure that TAC Vista Server is started"

[Product_Support]

Issue

When attempting to connect from a TAC Vista Remote Workstation, the following error appears:

"Ensure that TAC Vista Server is started"

This occurs even when DCOM settings appear to be configured correctly.

Product Line

TAC Vista

Environment

• Vista Server
• Workstation

Cause

This issue typically arises when both the TAC Vista Server and the Remote Workstation are part of a workgroup rather than a domain. In such configurations, authentication and DCOM communication can fail if certain conditions are not met.

Resolution

To resolve this issue:

1. Verify DCOM permissions are correctly configured on both the server and the workstation.
2. Ensure that the Administrator account password is identical on both machines.
   • This is necessary for authentication in a workgroup environment.
3. Restart both the TAC Vista Server and the Remote Workstation after making changes.

Additional Notes

• This issue does not typically occur in domain-joined environments, where centralized authentication handles these permissions.
• For more information on DCOM configuration, refer to the TAC Vista DCOM setup guide
