Hi to all, Me again
Finally after some time troubleshooting I was able to find out that what my problem was and I must say that I am really feeling silly since it was permissions on DP site where site needs to have under local administrators account a AD computer object of SCCM server and I didn't know that I had to turn IIS and WEBDAV to allow BITS to work OK.
Well that's behind me and now deployment work in on some of my servers where my DP sites are not DC-s, so my next question is since a DC has no "local admin" accounts, how do I give the site server computer$ account admin access to the DC and/or what should the permission on the DC\smsShare look like??. In mean time I will google off course )
