Hi All, On one of our Small Business Server (W2K3 SP1) we have some strange behaviour. After (re)starting the services (Client Acceptor and TDP Exchange) all backups run fine for 2-3 days and then the services get stuck and have to be restarted. On another SBS we do not have those problems. Failing SBS: TSM Client 5.3.2.0 Good SBS: TSM Client 5.3.0.15 (this also did not work on the other SBS) TSM Server is 5.2.6.4 on AIX. Anyone knows a cure? Richard.
