Alright, so I built this server a month ago. I installed Server 2012 R2 on it and the necessary roles to use windows deployment services. I have a mini-windows 7 environment which we use for testing and boot through network PXE boot. The server is acting really odd now. When we PXE boot, it takes about 2 mins to get past the DHPC... section. It also will fail if you try and PXE boot more than one computer at a time during this 2 minute window. I have uninstalled all the roles from the server and put them all back. I have tried 4 different switches, many different ethernet cables, and almost every fix on the internet I could find. I even tried another ethernet port on the server. No change. Does anyone have any ideas on this?
Thanks in advance!
