Just built a new BM3.9.2 server using NW65SP8 into an existing tree. All
timesync and replica's all looking fine.

The server added fine as a VPN Server in iManager. However, further
to creating a C2S Profile (tried Default and new one) as soon as I click
OK to exit C2S config, I get:

System error

A system error occurred

Any ideas guys?

Tried rebooting and DSRepair etc
