To allow DCOM traffic through ISA Server


Many of us could have encounterd¬†problem while executing VB Scripts or WMI Queries from ISA Server and got “RPC Unavailable” error.

In order to allow DCOM traffic, you can create a rule in ISA to¬†“Allow RPC to ISA from trusted servers”.

Disable “RPC strict compliance (to allow DCOM)” after which WMI Queries and VB Scripts execution will be successful.

Happy Learning!!!
