The PXE appears to be normal, but when someone tried to PXE boot to our site server, it found the server, but after it got an IP address, it got to the TFTP portion and failed there. Looking at the server, the TFTP service on the server was set to automatic, but was stopped and when trying to start it, it started and then immediately stopped.

About Error: Windows error code 10049
This is a windows binding error: Cannot assign requested address.The requested address is not valid in its context. This normally results from an attempt to bind to an address that is not valid for the local computer. This can also result from connect, sendto, WSAConnect, WSAJoinLeaf, or WSASendTo when the remote address or port is not valid for a remote computer (for example, address or port 0).
During installation of SBS it binds to a specific IP address. In this case the IP address of the server had changed which resulted in the TFTP server not starting.
Resolution Steps:
1) If you know the original static IP address before it changed. Set the Site Server back to that original IP
2) If you do not know the original IP address then uninstall then reinstall SBS
