ERROR service ‚?‘ unknown or service sapms unknown

Error:

When connecting to SAP, you get the following error:

ERROR service ‚?‘ unknown

Reason:

The problem is that there are entries missing in the services file in the folder

C:\Windows\System32\drivers\etc\services

Warning! Service not executable. Don't add any file extension, like .txt to the services file.

Solution:

If you get the following error...

ERROR service sapms<SID> unknown

...append the following line to the services file:

sapms<SID>  36<nn>/tcp

nn is the instance number of the SAP system (e.g. 00 or 99).

Example:

For System ID (SID) ECC and instance number 12 the entry would look like this:

sapmsECC 3612/tcp

Note: When inserting this into this file, please ensure that the last entry is always terminated with a return. For some platforms, this may cause problems, as the last entry may not be recognized.

After editing the file, you may need to restart the Xtract service or the machine.
