If you change the name of the computer on which adTempus is running, the adTempus service may fail to start, as described in article K00000222.


The following sections discuss possible reasons for the failure.

License Invalidated by Computer Name Change

When you activate adTempus on a computer, your license is tied to the name of the computer. Changing the name of the computer invalidates the license, causing adTempus to report a licensing error and fail to start.

If you run the License Manager from the adTempus program group, the license will not appear in the list of licenses, or will appear with a message indicating that it is invalid.

To correct this you must return your license and then re-activate the software on the computer. To do so:

  1. Log in to the online license management system at using your License Account Number.
  2. Follow the instructions in the license system to "return" the license to your account. (Note: You will not be able to remove the license from your computer using the License Manager as instructed by the license system, because the license will not appear in the License Manager. This is OK.)
  3. Run the License Manager from the adTempus program group and select Activate Software from the License menu. Follow the instructions to activate the software.

Database Settings Point to Old Computer Name

If adTempus is configured to use a SQL Server or MSDE database on the same computer as adTempus, the computer name may be stored in the adTempus database configuration, causing adTempus to try to connect to the old computer.

To correct this, run the Registry Editor and locate the key "HKEY_LOCAL_MACHINE\SOFTWARE\Arcana Development\adTempus\lDatabase" (if this key does not exist, adTempus is not using a SQL Server or MSDE database, and this section does not apply to you).

Edit the ConnectionString value and look for a section that reads




Where computername is the old name for the local computer. If this is present, replace computername with ".":




Do not modify any other parts of the ConnectionString value. In particular, do not modify the "database=" section, which may also contain the old computer name.

Beginning with adTempus 3.0, the database configuration tool will not include the computer name in the ConnectionString setting, avoiding this problem in the future.

Database Cannot be Found

If you are using SQL Server Express, renaming the computer may cause SQL Server to report that it cannot find the adTempus database. In this case adTempus will report a database error similar to the following

Could not find server 'servername\ADTEMPUS' in sys.servers. Verify that the correct server name was specified. If necessary, execute the stored procedure sp_addlinkedserver to add the server to sys.servers. (source=Microsoft OLE DB Provider for SQL Server; native error=7202; SQL state=42000)
