I am hosting an ecommerce site withe the following internal setup:
OS: Windows 2000 Advanced Server (sp 4)
Web Server: IIS 5.0
DB: SQL Server 2000
Router: Windwos RRAS
DHCP Server: Windows DHCP Server
DNS Server: Windows DNS Server
Internet Connection: Cox.net High Speed (4 down / 768 up)
Anitvirus: Norton (latest)
Firewall: ZoneAlarm 5.1.1 (latest)
I have several static ip's configured and each hosting different websites.
I switched to a higher level of isp service recently and ever since i am experiencing intermittent dns errors when hitting my main website. It seems to get worse over time. Typically, an IIS reboot will cure the problem temporarily (1 - 2 hours). In addition, connections to the server through remote desktop are intermittent. The connection will go through sometimes and then disconnect or at times I can't connect at all. This setup worked very well for about a year. Since I've upgraded internet service, upgraded Norton anti-virus and upgraded ZA Pro, I've been having this problem. I've check w/ Cox and after running test they say everything is fine. It seems to be an internal configuration issue. My site is frequently down and I'm losing money so this is urgent to me. Thanks in advance for any help.
