I have a network of 1 server and 8 PCs, all running CentOS 5.2. There is one workstation where I have tried several PCs and I still get the same problem. I can take a computer that is working fine when plugged in somewhere else, and plug it in at this workstation into this network port etc and the same trouble exists:
runs ridiculously slow, services particularly such as "NFS statd", "avaihi daemon", "cups" and "system message bus" take a ridiculous amount of time (Avahi daemon norally fails), network logins (via LDAP) fail or take ridiculous periods of time, and system is generally unusable. This 'dodgy' computer successfully gets an IP via DHCP, can ping server fine, and name resolution of the server appears fine too.
The rest of the computers are fine. Using OpenLDAP & NFS without problem. What could be causing this - is there an obvious solution (it evades me?) Many thanks for any help
