accessing Netware box and Windows domain

we have a situation where our users need to map an smb share to a
Windows domain. We'd like to also get them storing files in our Novell
infrastrucuture, to take advantage of NSS. Accessing the smb shares
always worked very quickly, but since installing client 32 and mapping a
few drives, all network drive access becomes slow. we're using XP,
latest Netware client, and NW6.5SP4

has anyone found a work around for ncp and smb playing nicely together?
