Greetings, I'm just curious if netscreen 500 supports RPC, WINS, and windows network stuff.. ? I'm currently having problems with replication of our NT domain servers. After plugging the Netscreen 500 into the network.. the NT domain won't replicate.. is this because Netscreen doesnot support the RPC used by the NT domain? You feedback would help me immensly. Thanks guys. BR NR I had a similiar problem with my Netscreen 5.when performing this function through an IPSec tunnel.. Per Netscreen support, they had suggested enabling the following via the CLI: set flow tcp-mss set flow path-mtu Turns out Microsoft netbios does not like fragmentation. Which the Netscreen device has it enable by default. See the manual for more info on those commands if your interested. -fifo
