Hi All, I am trying to installa NEW exchange server 2003 in 2 node active/ passive cluster. Both nodes are with Win2K3 withSP2. I have configured Majority Node Set. I have configured CLX to failover and fail back automatically. I have configured File Share Witness, which has a common shared folder accessible by both nodes. Thus fail over and fail backs are happening automatically. Now problems / issues are, 1) Is it necessary to haveTWO virtual disks presented to nodesin EVA? a) IfYES what should be Size of the disk for around 300 users. (Current VDISK size is 250GB ) b) If NO, how to create a Cluster Group and move ONLY alone MSDTC resource without dependent RESOURCES. (By default MSDTC resource appears in default Cluster group, but as per Installation guide it should be moved to new cluster group and new physical disk and network name resources should be created) 2) How to delete old default SMTP Virtual Servers which are appearing System Manager. As they are reappearing in System MAnager even after reinstalling OS on both NODES.(These virtual servers were created during test installtions of E2K3) Please Help. Thanks in advance.................... Sanju
