WDS 2012 errors, wondering if someone can help me

[Jamie_Evans]

Tried looking this up on technet/other threads on edugeek but can't find anything similar to my situation so curious to see if people have any idea what might be causing this.

 

Basically the first 3 clients I F12 boot go through perfectly fine and appear in the "Pending que" on the wds server itself but everything after that either fails or takes up to 5 times to get going in which case it blue screens anyway.

 

Here are the pictures in order, any ideas of what it might be are appreciated.

A little more information about the server:

ONLY WDS is installed, dhcp is on another server

Win ADK 5.0 installed

 

 

Thanks in advance,

 

Jamie

Do you have spanning tree enabled?

Are you allowing connections from unknown clients.? Or prestaged?

Known & unknown but with Admin approval for unknown

 

Do you have spanning tree enabled?

Pretty sure I do (for network storm purposes), how would this stop more than 3 computers connecting though?

Well if you dont have fast port enabled on each port on the switch it can cause issue with pxe boot.

Just the switch the clients are connected to? or EVERY switch in between the server (which is stored on a VM in another building) and the clients?

Just the switch for the clients afaik.

Hi

 

Have you set the dhcp options in your dhcp server. I'm not at my desk at the moment so not sure but I think they are option 60,66,67, I think!

Should use ip helpers really.

What are IP helpers lol

 

@harriuk

Yeah I did option 66, and 67 don't remember doing option 60 though?

Configure your router if wds and/or dhcp on other subnet.

O that's right, I didn't use option 60 because dhcp is on another server.

 

Only 1 subnet network wide, although I think you may be onto something - we changed our IP scheme a while ago and didn't bother to update the switches, will be looking into this tomorrow and let you know!

 

Thanks for your replies Free780!
