Machines going to sleep

[TonyB]

I am a system admin on an Air Force Base in Japan. We
recently had a team visit that upgraded our classified
network from a Windows NT 4.0 domain to Active Directory.
Of course, with the upgrade, a number of GPO's were added.
The problem that we have is if a machine on the network is
not used for some unknown period of time, to seems to go
to sleep. When a user logs in, they log into a cached
account and can't see the network. However, if we ping
that machine from here, it give a couple of 'no reply'
responses and then a couple of replies and that seems to
wake it up, as it were. The user can then log off and log
back in with no problem. If anyone knows what is causing
this, we would appreciate some assistance on this. Thanks.

Tony

Does the network card have the Wake On LAN (WOL) functionality? I'm
just guessing here. Does this happen to more than one PC? Do they
all have the same type of network card?

I do not believe that the NICs use WOL but I could be
wrong. We actually have a wide range of NICs being used on
our network from on-board Cat5 in desktops to PCMCIA, MTRJ
Fiber NICs in laptops. We have similar situations with all
machines regardless of the NIC. We currently have a batch
file that pings one of the main routers every 5 hours but
we'd like to have a real solution rather than the band-
aid. Once again, if anyone can offer some assistance, we
would appreciate it.

First and foremost, I am so sorry for the delay in reply.
The Holidays were busy. I do appreciate the help but that
really didn't help. I'm not sure that the machine account
is not the problem but a simple ping in either direction
regains connectivity. Thanks again.
