One of my clients recently got a new Cisco ASA 5510. All was working ok until two days later when I implemented a few Windows 7 machines on their AD domain. Randomly (more times than not) the Win7 PCs lose internet and access to the domain controller…I am unable to ping yahoo.com or even the internal SBS2003 server. I can however ping the firewall consistently.
The PCs are plugged into the same switch as the SBS server…statically assigning an IP doesn’t make a difference. Any suggestions? I’m not sure if the ASA is my suspect or not…but all the issues started as soon as I implemented it. All windows XP machines work perfect with no issues.
