We've discussed about this for long on these pages. Anyway, I'll try to summarize. First, you speak of RPC errors...this sounds to me you've to check in your DNS, something has not been registered or well replicated. You've Windows server as member ones of an AD domain: so, why using a local user? Create a domain users "snapdrive" and put it in the local administrators group of servers and filers. You can create but you can not mount...sounds like timeout errors recalled by Snapdrive...double check you config. Did you remove some client access or file&print services protocol fm your Windows server NIC setup? Did you setup MPIO of MS initiator together with DSM? This is a terrible thing! :-) It does not work. Fori SCSI you don't have to spend money for DSM, the free MPIO fm MS Initiator works very well! For fiber instead it's better (a must have) to use DSM...obviuosly if you have 2 HBAs for host. Anyway it has to work.
Alternatively the free MS initiator (configured of course to see NetApp and this one configured to mask LUNs) or the fiber HBA drivers let you 'see', mount and format disks under the disk management interface. How expand them? Simple but manual. Open the Filerview or via CLI and expand the LUN. Disk management will show you free unowned space. Open a DOS prompt and with Diskpart expand the partition...
That's all folks Bye

Not very stable? I suggest you to review your environment for we've lot of W2K3 systems and heavy apps (SPS, E2K3, E2K7, SQL fm 2K to 2K5...) using Snapdrive (fm 4.x to 5.x) and SManager since months with no issues at all...(fiber and iSCSI)
all our servers are vanila installs (new setups) win 2k3 64 bit fully patched, mpio from MS is installed iscsi from MS is installed snapdrive 5.0 is installed hosts are tied into AD. local user on host is snapdrive, also created a user on the filer "snapdrive", added user to Administrators group. snapdrive runs as the local user "snapdrive" created volumes, shared them to everybody via cifs when i go to snapdrive on the host side, i keep getting RPC errors, however i can see the volumes, and can create luns, but can not mount the luns.
to summarize
do i actually need snapdrive to mount luns ? or can this be done, via windows drive mapping ? if via drive mapping, how would i expand a volume ?
