Failover of ASCS takes very long on a Windows Server 2008 Cluster

Hello everybody,

I have configured a ABAP SCS (NetWeaver 7.0) running on a Windows Server 2008 Cluster. The database runs on SQL Server 2008 which is also configured for use in the MSCS. The ASCS and the database run fine in the Cluster. So far so good.

When I want to move the SAP Group which contains the ASCS from on node the other node, then the failover will take very long (approximately 2-3 minutes). The Service of the group will go offline in a few seconds, but the Instance needs about 1 minute to go offline and on the other node it needs more then one minute to become online.

The failover of the databaseinstance will take only about 10 seconds.

Have you got any ideas why the failover of the SAP Group will take so long?

Thanks for your help in advance!

Kind Regards,
