SAP Error Messages

ERROR service ‚?‘ unknown or service sapms unknown

It could be that you get the following error while connecting to SAP:

ERROR service ‚?‘ unknown

The problem is that there are sapdp* (eg. sapdp00 3200/tcp) entries missing in the file services in the folder C:\Windows\System32\drivers\etc\services

Please append the entries in the file services you can find at the bottom of this article to your services file.

If you get the

ERROR service sapms<SID> unknown

you have to append the following line to the file services. nn is the instance number of the SAP system (e.g. 00 or 99).

sapms<SID>  36<nn>/tcp

For exapmle, if your SID is ECC for example, the line looks like the following one:

sapmsECC  3600/tcp

For System ID (SID) ECC and instance number 12 please set:

sapmsECC 3612/tcp

IMPORTANT!

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.
