RE: no longer listening

Mladen,

The equivalent of nsswitch.conf on Win2K is the "hosts" file in winnt\system32\drivers\etc. You'd probably say: the /etc directory in M$ Windoze? Somewhat of a resemblance to the UNIX naming convention. You'd be surprise to find a "services" file just like the one found in /etc directory of the UNIX and UNIX-like OS's....But, well this is way off the topic we are dealing with. Like Jared said, we need to focus ;)

My name resolution is done by a DC, actually there are several of them. I should probably check to make sure everything is consistent across all DCs as far as computer name and address for my Oracle server host. I doubt there will be differences since they replicate the same domain info. I also checked the hosts file and it only has the localhost line in it. I'll try including a line for my server as it appears in my domain controllers, maybe that'll help.

So, how are your host names resolved? Any changes in DNS or WINS name servers? Did anybody reboot or alter PDC? On NT host names are resolved by asking PDC. If it cannot respond because of reboot, listener may shut down as well. You should try modifying yur local equivalent of nsswitch.conf. whatever the name is.
