Thread: MSRPC Server Service BO

I got an attack attempt on my computer today - Norton Internet Security identified it as coming from attacking computer 10.200.254.244, 2243. The source address is 10.200.254.244 and then it says the destination is my E521 (10.200.254.217, 445)??; traffic description = TCP port 2243. This is a serious attack/vulnerability if it is for real - but is it? Or, is this somehow connected with my network? I'm a little confused. NetRange: 10.0.0.0 - 10.255.255.255 block is reserved for special purposes by IANA.

FYI-figured out what this was - the VoIP equipment trying to phone home for software updates....LOL
