When using Win32_NetworkAdapterConfiguration.EnableStatic() to give an adapter a static IP configuration, the function returns an "81 - Unable to configure DHCP service" if the adapter is already configured with a static address. However, the function still succeeds in setting with the new operation.

When using Win32_NetworkAdapterConfiguration.EnableStatic() to give an adapter a static IP configuration, the function returns an 81 and still function is working but consequences is when using SetDNSServerSearchOrder() it will return 94 and still both function are working!!!

When trying to use Win32_NetworkAdapterConfiguration.EnableStatic() remotely to change the IP-address of the remote computer, while being connected through that adapter, you obviously loose connection and will get an RPC not available error-message (the settings are changed however). You might want to change the Gateway and/or DNS-settings prior to setting the adapter's IP-address...

My NIC have two IPs, I use EnableStatic() to release the master IP and make the second IP to be the master IP. Then I will create a socket, when execute connect(), it will return a A socket operation was attempted to an unreachable host error. After I wait a while and call connect again, it is ok? Anyone meet the same problem? The OS I use is vista x86, also vista x64 and longhorn x64 have the same problem.

When trying to use the EnableStatic method on Windows Vista (c# using ManagementClass) for a second time "sometimes" the method returns with an error code that is not on the list: 2147786788... (I use EnableStatic to change the IP for the firs time, it works... then I close the program, then I run it again and fails).

I only have found that the problem maybe is because some other application is "holding the write lock in the TCP notify object".

Some others times it sets the Ip but the network does not work properly (the machine can't see other machines).. so i use the EnableStatic method again.. and the lock problem happens.

If the first call to EnableStatic method holds the write lock to set de Ip configuration.. how can I do to release this lock after the configuration is made???
