SAP Load Balancer
you need to have and entry in the [services] file for any system that makes use of SAP load balancing.
On my English Win XP install the file is located here;
C:\WINDOWS\system32\drivers\etc\services
Entry required in this file;
sapmsPR2 3608/tcp
And just in case you don’t have these entries as well;
sapgw08 3308/tcp
sapdp08 3208/tcp
