Second thing, this physical server has run Windows Server 2003 R2 Standard (64-bit) for 2 years without any issues. This is not a hardware issue.
- 2x Opteron 845 Dual-Core (4 physical cores at 2.0GHz)
- 12GB DDR ECC/R 266MHz
- 250GB SATA-II System Hard Drive
- 2TB SATA-II RAID Storage Array
OS: Windows Server 2008 Enterprise (64-bit)
- Active Directory Domain Services
- Application Server
- DHCP Server
- DNS Server
- File Services
- Network Policy and Access Services
- Web Server (IIS)
- .NET Framework 3.0
- Group Policy Management
- Remote Server Administration Tools
- Windows Internal Database
- Windows Process Activation Service
- After 64-96 hours of uptime, entire operations lag heavily. See below for list.
- Browsing server shares from the network; remotely logging onto the server via Remote Desktop; logging onto any workstation joined to the domain; logging off any workstation joined to the domain.
- "Lag" is defined as: the workstation/server sits for 3-10 minutes with 0% CPU usage after initiating the command. Explorer.exe is always unresponsive during this time.
- When I restart the ADDC (Server 2008) the symptoms dissappear for at least 36 hours.
- IIS, FTP, and VPN services are unaffected.
I have attempted to disabled completely the IPv6 service on all the workstations and the ADDC. This has no effect. I was also running VMware Server 2.0 (Final) on the Server 2008 machine and uninstalling this service has no effect on the issue. This server build is about 3 months old, and unfortunately I cannot correlate the issue appearing after any specific action. I am very hesitant to dump everything and reload the system with a new domain as I have everything configured as I want. I do not have much free time to do such a thing. When the server works fine, everything is configured perfectly. Sometimes I can cause a preemptive strike by restarting the server every night, but that should not be how a server is operated. I am very frustrated by the issue and so are the users. Performance is excellent when everything operates normally. Even with four Virtual Machines, everything was great.
Again, any help is appreciated. I have scoured Google, spoken with other skilled Microsoft professionals, and done all the troubleshooting I can think of. Nothing seems to affect the issue.
Thanks in advance.
