I had upgraded the SEPM Server from SEPMR4 to SEP MR4MP2. Earlier NTP was not installed in client pc, so we just added NTP in newpackage & to pushed for client installation from the console. NTP was showing also in client pc. PC was losing IP address so we removed the NTP from the console.

Now problem is that, when all PC start some IP based devices(switches, network printer) not working. If i ping the network printer when all pc started , request time out is coming in some packet, but in some packet it's pinging.

If all client pc switch off network printer ping is ok and any packet lost.

right now no any firewall policy is running from the console to block any traffic.
