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


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.


The services file should not get any extension. The name should stay services and should not become e.g. services.txt

After editing the file you may need to restart the Peakboard Designer.
