TFTP Timeout Error on PXE Boot

Question

Ok this is what happened.  I tried to patch a image with windows updates - It filled up my hard drive.  So I canceled the process and attempted to remove the folder it created on my hard drive.  I went to try pxe boot a machine and I got the
blue screen:
After this I removed the check next to pxe to uninstall WDS and I waited for it to uninstall and reboot.  After that I clicked the check box next pxe so it would install everything again.  I redistributed the x86 and x64 boot images but now when
I try to pxe boot a machine I get the following in event viewer:
The Following Client failed TFTP Download:
IP *.*.*.*
Filename: SMSBoot\x64\wdsnbp.com
ErrorCode: 1460
I even made added the entry in the registry to change the TFTP block size.  I have no idea what to do at this point.  I am running Windows Server 2008 R2 and SCCM 2012 SP1.  On the client machine I am getting TFTP timeout.

Answer 1

1460 (0x5B4) =ERROR_TIMEOUT
This operation returned because the timeout period expired.
