Hmm, it may be that just a few servers are affected here. we have one
important server which appears to have a weird DNS setup:

dig +short -t A server.domain.net
172.100.10.25
dig +short -t CNAME server.domain.net
(NORESPONSE)
dig +short -t PTR -x 172.100.10.25
c10203.domain.net
dig +short -t A c10203.domain.net
(NORESPONSE)

While this is quite obviously broken, Windows clients in the domain have
no problems accessing this server, while Linux clients do. The only
temporary workaround I found for this is to add c10203 to /etc/hosts
locally and mount the share as "//c10203/share"
(//c10203.domain.net/share does *not* work).

This is samba 3.5.8, kernel 2.6.38.6-27.fc15 on Fedora 15.

No, see above.
