It's on the client.
The server is running Windows 2003.

OK, I tried to build it with 2.6.21-rc4, it failed.

CONFIG_CIFS=m
CONFIG_CIFS_STATS=y
CONFIG_CIFS_STATS2=y
CONFIG_CIFS_WEAK_PW_HASH=y
CONFIG_CIFS_XATTR=y
CONFIG_CIFS_POSIX=y
# CONFIG_CIFS_DEBUG2 is not set
CONFIG_CIFS_EXPERIMENTAL=y
# CONFIG_CIFS_UPCALL is not set

I tried to build it with gcc-4.1.2.
I just downloaded the cifs-1.48.tar.gz archive, and replaced the 
contents of fs/cifs in 2.6.21-rc4 tree.
