Solution: ========
First of all, I must say that I did read the Solaris 2 FAQ - http://www.fwi.uva.nl/pub/solaris/solaris2/ and my /etc/services file is updated with the infomation below:
5.38) I can't run nfs: netdir_getbyname failure, /dev/udp: bind problem For some reason the nfs service has disappeared from your /etc/services file, nis map or NIS+ table. You need to have an entry like: nfsd 2049/udp nfs # NFS server daemon (clts) nfsd 2049/tcp nfs # NFS server daemon (cots) If you use NIS+, you must make sure that the NIS+ entry is readable for the machine executing nfsd. If you used your SunOS 4.x services file, that would explain it: SunOS 4.x doesn't have an entry for nfsd in /etc/services, Solaris 2.x requires one. This will usually not happen until you upgrade to Solaris 2.4 or upgrade to 2.5. Solaris 2.3 and earlier would always consult /etc/services, regardless of what nsswitch.conf said. /etc/services does contain the right NFS entries. Solaris 2.4 and earlier don't have an entry for NFS over tcp.
--- end of excerpt from the FAQ
And my /etc/services file did contain the lines above.
Another (very important) thing I forgot to mention was that I did set up NIS+ in compatibility mode with NIS and used /usr/lib/nis/nispopulate -Y to create NIS+ tables with the contents of NIS maps.
With the tips sent me by Francis Liu and Casper Dik, I recreated the services NIS+ table with the contents of the /etc/services file using the command:
/usr/lib/nis/nisaddent -rv -f /etc/services services
I want to apologize with Francis Liu and Casper Dik for taking so long time to realize what they meant when telling me take a look at the NIS+ services table.
To finish this summary, I'd like to share the tip of Casper Dik:
You could try (in /etc/nsswitch.conf):
services: nisplus files
(files always get consulted if nisplus can't satisfy the request) That would give you the best of both worlds, IMHO.
Casper Dik
