Just to let everyone know, my Xbmp (May 01 Build) gave me about 5 hours of frustration today after it started freezing when accessing network shares. Went through all the steps mentioned in here, no go. As soon as I tried to access the network (Relax) share, freeze. Local HDD worked fine. What I ended up doing was using Xbmp as the dash instead of Evox (Thanks Jaydee) as a last result. Worked immediately. Looks like there must be an issue with Evox (networking layer) and Xbmp. Good luck to anyone having the same problem! I feel your pain.
