Hi,

One small correction and addition. Check for group 'SPACE'. Check for appropriate entry in services and also hosts file from C:\WINDOWS\system32\drivers\etc. If possible, restart both the servers and check.

Make service entry for sapmsMT4 ( MT4 = SID for R/3) on the J2EE host. and also Check whether PUBLIC group is availablein your R/3 System. Transaction SMLG.

Give a system reboot for J2EE host.
