Problem Connecting To Network

[normem]

First of all.. sorry about my english.. and sorry if I ask some stupid questions )

 

I work at a small school.. and this week we have some problems connecting our computers to the network.

It seems quite random if the computers get logged on to network or not.

 

The weird thing is that the first 5-10 PCs that we turn on is connected OK to network.. then there is almost random if they get connected or not.

 

I was looking at out server today and there are MANY errors.. (see attachment)

--

 

Is there some quick solution to this?

i would say this is DCHP related. i take it the server is assigning DHCP, check what the logs are for the DHCP role. also check the scope of the DHCP.

Hi,

 

Given the pictures above, I can't understand anything because I can't see errors IDs.

 

Anyway, I think Dean is right, check your DHCP server (windows server or router).

 

Also try the following.

 

Connect each computer until you notice that anything is working anymore, at this point go to one pc which is working and open a command prompt and type:

ipconfig /release *

now unplug the network cable and try to attach another pc to the network. Let me know if it receives an IP or not.
