We use the PXE boot funtion on our desktop PCs and laptops. Multicast TFTP is enabled within the BIOS to grab a boot file and only recently we have been witnessing an "Open TFTP Timeout" during the bootup process.
I have checked over the IGMP / IP PIM configuration across our network and everything looks fine. However when I check the IGMP group that the client is trying to join I see address 18.104.22.168. Yet when I look at the IGMP group on the port to which the Altiris Deployment server connects I only see group 22.214.171.124.
A colleague has shown me the configuration for the MTFTP server on the deployment server and the group address is set at 126.96.36.199.
Shouldn't the group address on the Altiris deployment server also be 188.8.131.52 or is the 184.108.40.206 address within the 220.127.116.11 IGMP group and the problem is in fact something to do with the network ?
Any help would be appreciated.
