I am hoping to get some advice on some of the WDS issues we have been having over the past 4-5 months
We have a relativity simple network topology
Out workstations on one subnet and servers across a WAN link on a separate subnet with a juniper firewall in the middle
The WDS server is 2008r2
The problem we are having is that every few weeks we seem to lose the ability to PXE boot across the firewall to the WDS server
The WDS server gives us the following error
The Following Client failed TFTP Download:
IP: 10.10.34.95
Filename: \Boot\x64\Images\DaRT7.wim
ErrorCode: 1460
Which seems to be related to a time out
1460 is ERROR_TIMEOUT. This message means that the client started downloading the file, but didn't finish and the server is terminating the connection since it hasn't seen any packets from the client in a long time.
https://social.technet.microsoft.com/Forums/windowsserver/en-US/a1246f62-6a8a-482b-9323-7e02dfeab196/wds-tftp-errorcode-1460
I have a hard time believing this because it works successfully for weeks at a time.
I have looked a wire shark trace to see what is happening on the wire, and it look like the TFTP packets are transmitting until a random point and then stop.
I immediately suspect the firewall, however I'm told by our firewall people that the firewall is not configured to stop TFTP packets,
Any Advice would be greatly appreciated
Below is an example of the the TFTP traffic at the point of failure
To add to this I was able to obtain the trail of the tracing log
