I'm having this error all the time, for which I cannot find solution:

In Event Viewer -> Application log

1st - info message:
listening on IPv4 interface TCP/IP Interface 2, xxx.xxx.xxx.xxx#53

2nd - error message:
could not listen on UDP socket: permission denied

3rd - error message:
creating IPv4 interface Loopback Interface 1 failed; interface ignored

and then again for every IP address, and on and on...

(note: xxx.xxx.xxx.xxx is server's IP address)

Does anyone have a clue what might cause this and how to fix it?

Edit: here's the screenshot

 

Same here, I still ignore them

 

It is DNS server problem, probably Bind 9.2.4
Check your firewall in Plesk CP there must be rules which allow both UDP/TCP 53rd ports
If your WIndows 2003 is not with SP1, check Windows firewall for same ports

Microsoft DNS Server 5.2.3790.1830 @ Windows 2003 Server

Okay, you got me lost here... I've checked the Plesk firewall and saw there are 2 rules:

DNS TCP -> 53 / TCP
DNS UDP -> 53 / UDP

It's clearly they both use the same port. What exactely should I do now? Change the port of UDP to, lets say, 54?

 

No, it is OK, TCP and UDP use different sockets to bind ports.
Well, the next step:
Check TaskManager and event logs for "named" (exactly)

John, I wrote it down (and attached screenshot) in my first post.
As for the Task Manager, what exactely should I be looking at?

 

Sorry, didn't pay attention to your .gif

Mea culpa

1.Go to computer management, Services, look for Plesk Name Server
2.Right click->Properties->Set Startup_type Disabled->Stop service-click OK

Thanks... it resolved the problem how did you know what to do? And what was "Plesk Name Server" for?

 

"Plesk name server" is a BIND DNS service.

 

Weird... Thing is I don't remember whether whis happened before v7.5.5 update...
I've used MS DNS server in "Components management" within Plesk from the beginning.
