Hi hopefully this will be an easy one.
I have had my domain running for last few months no probs 200 + users / machines (in fact still running ok) but as per the number of machines i have my subnets getting cramped our campus network guys (they manage the network up to the building) have created me a new VLAN on another subnet currently all the machines on xxx.xx.230. the new subnet is xxx.xx.229. ive created a dhcp superscope with the scopes for each subnet and settings gateway / router etc.
started testing today by shrinking the pool on the 230 subnet and releaseing / renewing till it was full did what it should and overflowed into the new 229 subnet, yeehah i think but then notice takes 5 mins for the machines on the new subnet to configure network connection etc etc and then when logging in active dir etc doesnt come through properly. ok dns i hear you say :) well dns is set correctly in the dhcp stuff i created a new reverse lookup zone for the new subnet everything appears to work ie ptr records update etc from the client i can prin and trace everywhere as expected but still the AD / Group Policies not coming throu properly.
login script fails and get a userenv error 1053 "windows cannot determine the user or computer name.(the rpc server is unavailable).group policy processing aborted"
whats that u say pull them off the domain and rejoin it? ok well did this and cannot join it back to the domain either as i get the rpc server unavailable trying to join the domain, dns is fine i can ping the pdc etc.
any ideas would be greatly appreciated
