MSE kernel upgrade after new installation

Question

          upon bootup and stopping the mse server, I receive the following error messages:
iptables v1.3.5: can't initialize iptables table `filter': iptables who? (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
iptables v1.3.5: can't initialize iptables table `filter': iptables who? (do you need to insmod?)

also when trying to ping the server, it not reply ???
this is new installation of cisco MSE 7.4
please any advice

Hi,
I would never recommend doing an OS upgrade of a domain controller.
The preffered method is to:
1. Build a new 2012 R2 Server
2. Install the Domain Controller role
3. Promote the server to a domain controller - this will extend the schema of your AD to support 2012 - whilst generally fairly safe to do ensure you have relevant backups in place for your domain / forest
4. Transfer FSMO roles to your new 2012 DC
You can then go ahead and demote the 2008 DC, rebuild it to 2012, and re-promote it do a DC again. Keep doing this for all your DC's
Also you would need to upgrade your exchange first as Exchange 2003 isn't supported with 2012 domain controllers.
