Re: p2psvc.dll idl function definition ambiguities - any ideas?

[Rich Smith <richard.j.smith () hp com>]

Cheers for the pointer to MS download note, while PNRP may have been  
updated to V2.0 this doesn't reference which MSRPC interfaces have  
changed. An application version change doesn't mean the constituent  
MSRPC interfaces are changed per se, and from the unmidl'd p2psvc.dll  
the version numbers on interfaces a2d47257-12f7-4beb-8981-0ebfa935c407  
(pnrpsvc) & 8174bb16-571b-4c38-8386-1102b449044a (IP2pIMSvc) are the  
same in both versions. Which brings me back to the original question:

If v.2.0 of PNRP has changed the MSRPC interface definitions, why  
haven't the version numbers on the interfaces been bumped or new  
UUID's been designated?

idl's of the two versions of the p2psvc.dll are attached if people  
want to have a peek.

Cheers
Rich
