I have an HP DL360 G7 server with NC364T and NC382i NICs. This server holds our DFS, with EMC powerpath 5.7, and Qlogic for the HBA cards installed. I have found this server will randomly drop off the network, where it will respond to ping but i cannot access any file shares (or DFS), or log onto the server via KVM, iLO, or RDP. I will receive a login screen, enter credentials, then when i click OK it simply goes to a blue screen background (NOT BSOD).
I have tried to update the NIC drivers from HP with cp018229 and cp018873. I have also tried to update the NIC drivers from the manufacturers with HP cp021535 and Intel PROWinx64 18.7 version.
I do not view any errors or failures in the system or application logs that would appear to cause this behavior and logging will stop when this occurs until system is cold booted.
Are there other logs I could look at to find the cause? Has anybody had a server behave like this and were you able to resolve it?
