Comms timeout

Netweaver and MaxDB. Good idea though - I'll check other power saving options.

The Netweaver App server is definitely not gonna like its IP changed from under it, or it being lost for a bit, might recover a renewal but a different IP is bound to trip it up, if that's what's happening.

So I reckon fixed IP, make sure ur gateway is correct and DNS works, take all power saving off, restart the lot (Windows!) and monitor it.

I think I had a network card powering itself off once, and it was only fixed with an updated driver.

If that's what's happening, it probably explains the DHCP error rather than the other way around. In my experience IP addresses don't change just because you're using DHCP, although I guess a DHCP server could be setup that way.

AFAIK, the IP address is fixed. I've shut SAP and the database down, as I'm skiing tomorrow and visiting a client on Wednesday. If the problem doesn't recur, then I'll assume it's a SAP/db issue.

Updating the network card drivers is a good idea too, I'll give that a go.

thanks
