New Revision: 54966
URL: http://svn.reactos.org/svn/reactos?rev=54966&view=rev
Log:
- Merge 54929, 54930, 54932, 54933, 54934, 54939, 54941, 54942, 54944, 54945, 54946, and
54947
- The DHCP service now recognizes adapter configuration and media state changes without
manual intervention
- Multiple bugs with a static IP configuration are fixed
- IpRenewAddress (ipconfig /renew) and IpReleaseAddress (ipconfig /release) no longer
corrupt internal DHCP state
- Routes that cannot currently be resolved by ARP no longer become corrupted by the
neighbor timeout
