Servers R1 and R2 have been up for months, but until recently access from subnet B was not tested.
I added IP address 192.168.2.142 and it gives the same results. So I move 192.168.2.142 to (working) server R3 and nMap says. . . Starting Nmap 5.51 ( http://nmap.org ) at 2011-04-25 12:53 Central Daylight Time Nmap scan report for 192.168.2.142 Host is up (0.0097s latency). PORT STATE SERVICE 137/tcp closed netbios-ns 138/tcp closed netbios-dgm 139/tcp closed netbios-ssn 445/tcp open microsoft-ds 1433/tcp open ms-sql-s Nmap done: 1 IP address (1 host up) scanned in 0.53 seconds The problem occurs ONLY on R1 and R2, even with a different IP So, I am missing how this can be on the router? Thanks!
