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? Thanks..... </BODY> </HTML>
