Data Protection Manager Clients on Linksys E1200 Not Getting Synced
Posted on 2012-04-11
I know this is long but I wanted to get as much info in.
We just added a Linksys E1200 on our network to provide wireless access to users that will allow the laptops to continue to communicate with our internal servers when they are not connected to the "wired" network which is connected to a Cisco ASA 5510.
The Linksys is just connected like all other clients through a TrndNet GB switch. The Linsys receives an DHCP IP (192.168.0/24) from the ASA and in turn gives clients an IP from it's own DHCP (192.168.4/24). All seems to be working for the laptops when on the wireless - Exchange, AD, Printing except for the actual syncing of files to our Data Protection Manager 2010 server.
.As soon as I connect a laptop to the wired (192.168.0) network it can sync. I also tried connecting a laptop through the port on the Linsys (wired) and still did not sync.
DPM is logging Event ID 10009 "DCOM was unable to communicate with the computer laptop.mydomain.dom using any of the configured protocols". To try to narrow this down I disabled the firewall on the DPM server, the laptops and the Linksys (under Security - SPI Firewall Inspection Disabled). I also disabled IPv6 using the registry hack but still have this problem. I don't know where else to look at on the Linksys as there is not much to configure. From what I've read this could be an issue with Dynamic RPC ports getting blocked.
The clients can see the DPM server as far as pinging or even mapping a drive to a share (it is also our Print server which works fine) so everything seems to be working except for the sync.
Is there anything that I am missing here?
