Probably you need to add this line sapgw00 3300/tcp # SAP System Gateway Port To the File C:\WINDOWS\system32\drivers\etc\services

Hope it will help

Hi,

The error is: ERROR service 'sapmsQEC' unknown.

In the services file on the server add the following entry

sapmsQEC 36XX/tcp

where XX is the system number (usually 00)

Hi,

Login to the backend system to which you are trying to connect.

Open transaction SMLG and check the logon group as PUBLIC instead of SPACE.
