Issue when rebooting DC/DNS Servers with Managed Swith
I am having issues everytime i reboot one of my DC or DNS servers i need to reboot my managed switch, otherwise users cannot access the servers. Does anyone know where i should begin to look to resolve this?
DC/DNS Servers Windows Server Standard 2008
Managed Switch Netgear GSM7352S v2
I have UDP Relay turned on for DHCP because my windows servers handle dhcp requests rather than the switch
I also have both dns servers in the dns settings.
In order for the clients to work (on vlans) i needed to create static routes in my firewall Sonicwall NSA4500
every server becomes unavailable when i reboot one of the dcs/dns servers and then i reboot the switch and it is fine.
i ran a dcdiag and everything is in order first thing i thought was ad wasnt replicating correctly, but right now i am at a loss.

Can you isolate things by trying a different switch?
How are the VLANs configured?
How many DHCP servers are setup? one or multiple?
I need more details on the configuration to be able to help more.

What is the switch manufacturer and software version?

I will get a list of how the vlans are currently setup, and kaffiend i will give that a shot.
Is this a Cisco switch? If so I'd need the "Show Ver" information. There is a specific bug I am looking for.

no it s a netgear switch
Every time I have seen something like this, it has been switch related.
I what is the model # of the switch and the software version running on it?
The specific bug on the Cisco I was referring to was if you had a catalyst switch with CPUtype of 0x300
I remember dealing with this very issue on a Netgear Swtich - Model GS724T (v2, i beileve), we upgraded the firmware and from what I recall, that seemed to have made a difference, but it still appeared to be flaky. The customer had a brand new Netgear GS748T waiting to replace the 24 port, so we just swapped it out and put the 24port in use in a different area that did not require any vlan configurations.

I am in the middle of making the changes of auto negotation to manual i will let everyone know if this works. THe vlan config is pretty basic. UNless there is something i need to look at specifically
Try updating the firmware of the switch. Otherwise, I'm pretty sure the switch is bad.
Can you ping the Ip of the switch from the server affected servers?
