Due to a long day, I muffed the title a bit, so it should be Client acceptor and Microsoft Cluster ------------------------------------------------- Windows 2000 with Microsoft Clustering 4.1.2.19 Client -->> (soon 4.2?) Although the parameters are not supported for directly running a CAD service under a microsoft cluster i.e. attached to a resource group, has anyone actually done it ??? Other than being an issue of a MSCS controlled resource, surly if I configure the CAD instance much as the scheduler it will work, and can be configured manually if I have to. The requirement is to enable help desk to do the recoveries without accessing either of the cluster system providers, and all the users common, personel and shared data sits on the SAN/MSCS resources Dominic [EMAIL PROTECTED]
