Hi,

We are using an application (the application uses WMI componenets) to change
the IIS metabase of Server A from Server B. There is a firewall between
Server A and Server B. Couple of weeks back we tested the application and it
worked fine with ports 135 and 1331 open. Now its not working any more and we
are seeing that it is not working because ports 137 and 4332 are closed.
(Please note that it did not require ports 137 and 4332 before). When we
opened port 137, it started throwing error for ports 2255.

I will greatly appreciate if anyone can comments on the followings:

1. What are the ports required for WMI connection?

2. Is there any way to specify the port numbers?

Thanks
