Got a reservation, lookup is wrong - help!

[mats]

I have a wireless box called (for the sake of argument) boxa. It has a dhcp reservation (2008r2) with the correct mac address at 10.2.112.51.

 

When I ping boxa (by hostname) from the DC, it pings 10.2.112.52. It's only out by 1 ffs!

 

Tried ipconfig/flushdns

 

Any other ideas?

 

Many thanks,

 

Mat

Is the wireless box actually getting its ip though? and have you tried pinging by ip i.e. 10.2.112.51?

 

Sounds like possible dns error, have you cheked dns?

No dns errors. I've run out of time, going to set the ips statically on the wireless boxes.

 

Thanks for looking.
