Hi there!
We have recently updated to the newest MDT Version and everything worked fine for about a week. Suddenly the problems started. One of the biggest issues is, that multicast transmissions slow our network down to death. Yeah, i know about this problem/how to setup my switches. It all worked for about half a year now without any problems (Cisco Switches are configured properly, IGMP Snooping, etc.). Now, when there is a multicast session is started by one client, the others wouldn't even PXE boot. Getting an IP Adress (DHCP with spinning line) takes about two minutes and if succesfull, the transmition of the boot image ist veeeery slow or crashes with a 0xc0000001 error.
What i did so far:
- double checked the switch config
- restarted server/switches/clients
- reinstalled WDS services
- refreshed boot images from my deployment share
Any ideas are appreciated!
Thanks
