CRITICAL - Socket timeout after 10 seconds for windows serve

[lafargeuser]

I am receiving so many timeout alerts for Drive C: Disk Usage Critical 2m 17s 3/5 2013-02-11 09:52:31 CRITICAL - Socket timeout after 10 seconds & CPU Respectively.
However, after few minutes its coming normal stage. Coudn't able to find Root Cause & possible solution.

Do you know of an application "sounds like it is on a cron" that would be taking port 5666? This has been seen before as a cause for this issue.

[lafargeuser]

Port is not in use by any application.

Tried every possibilities, uninstalled agent & reinstalled check NSC.ini file...
Pls. help how to get rid of this alert..

Can you show us the actual command that you are running in the command line? (Hide sensitive info). Have you tried increasing the timeout? For example:

/usr/local/nagios/libexec/check_nt -H <IP_address> -s "<password>" -p 12489 -t 60 -v USEDDISKSPACE -l C -w 80% -c 90%

[lafargeuser]

Increased timeout value= 60 in NSC.ini
Socket timeout value

Where you want me to increase ?

However, if i monitor the Host using SNMP, then its showing in ok state.

You need to change it on the Nagios server's side, try running the command manually with a 60 second timeout as lmiltchev showed.
