no network connection after svchost.exe error

[rduque41]

I have a windows 2000 domain controller and about 100pcs working off
it. On some pc's in the morning when the come in there network
connections do not work. and i cant browse the network.
i look in the event viewer on the machines and i see

in the application log:
Faulting application svchost.exe, version 5.1.2600.2180, faulting
module ole32.dll, version 5.1.2600.2726, fault address 0x00032108.
&
Faulting application , version 0.0.0.0, faulting module unknown,
version 0.0.0.0, fault address 0x00000000.

and

in the System Log.
The server {8BC3F05E-D86B-11D0-A075-00C04FB68820} did not register with
DCOM within the required timeout.

this is not much help at all. i have antivirus running on the machines
and this has happened with brand new machines as well, i get no blue
screens ever.
When i reboot the computer it works fine(until the next time it
happens).

All the computers are completely up to date with windows updates.

this is happening on Dell GX620's, HP D220 MT, dx2000 MT, HP Dc 5100
MT.

They all mostly have broadcom netxtreme 57xx gigabit nic cards.

It happens randomly and not everytime to the same computer

any ideas on what could be causing this would be great.
coudl it have something to do with patches?
Please help, i am pulling my hairs out.

Randomly makes me think of hardware. Check your network cables,
switches, etc.
