DHCP renewal issues - limited connectivity
I have just imaged and set up 4 new machines for the staffroom. I ran newsid after so I know each has a completely separate SID.
Two of them logged on OK, the other two say domain is unavailable.
I go in locally and the network card is saying limited or no connectivity. I can pull the cable out, plug it in and sometimes this will get an IP, other times it will just sit there saying acquiring.
It seems to be happening randomly on some machines. I have checked DHCP and we are nowhere near capacity of leases (11% used).
I'm still trying to find all comms cabs in the school so I can't say whether its a dodgy switch, or loopback somewhere else.
The one thing I have noticed is that the cab in my office is flashing like there is a lot of data going through it, sort of how it did at my old place when I was ghosting. But there are no ghost sessions running and I'm not doing anything, and pings are still normal reply times.
I don't want to try too much because I've only been here a month so don't want to royally screw things up, but any advice on what I could look at would be very much appreciated!!!
