Look at the routing table below and you will notice that the route for 10.0.4.2 has been been dropped even though its listed as a persistant route. Why is this happening? What can I do to fix this?

This is happening on several of my servers and I depend on these routes so its critical that I find a solution. This route has a constant flow of traffic as well. Is there a rhyme or reason for this. Thanks in advanced for your help. Chad

This KB applies to Windows Cluster, but the same sort of thing may be happening: http://support.microsoft.com/kb/2161341 Although the route has been added, it is not listed as active since the interface parameter was not used when adding the persistent route. Have you tried re-adding the route using the interface ID (in this case 0x10003 as it is listed in the first part of the table for the route print command) -- Mike Burr

Hi, Agree with Mike , for confirm this suspicion ,could you post "ipconfig /all" result here ? Thank.
