problems when querying two variables at once, and the second query fails.
It is interesting to note that the original pnsclient doesn't have this

<DIV>NC_NEt ver 2.28 can only preform one check at a time. </DIV>
<DIV>thus if some of these checks take a long time to process, Like the
inplementation of eventlog checks in that version of NC_NEt then the checks
may get backed up. Thus causing several checks to get the No
Data Recieved form host. </DIV>
<DIV> </DIV>
<DIV>THe source of this may be due the Windows host, being very bogged down.
</DIV>
<DIV>A second source may be one of the checks periodically taking longer to
preform.</DIV>
<DIV> </DIV>
<DIV>A posible solution may be to increase the timout in check_nt.
command. this may allow it to check up quicker when the backup does
occure. </DIV>
<DIV> </DIV>
<DIV>A second solution is to setup some of the checks to be preformed as
passive checks using NSCA. this will eliminate that issue
altogether. </DIV>

<P><FONT face="Times New Roman">I am running Nagios 2.0 on Redhat EL3.
I am running NC_NET version 2.28 on the Windows clients. I monitor 222
systems with 1324 service checks. The problem I am having is that on
about 12 Windows clients I get the following error during checks "WARNING
11-02-2006 10:28:31 9d 6h 44m 37s 5/5 No data was received from host!
". This does eventually clear up but continually comes back. This does
not happen on all the Windows clients. They are all running the same NC_NET
2.28 version. Has anyone else seen this?</FONT></P>
