For Soul Dental Chelsea: Dentrix is running slowly. I started a remote session into the server, but I couldn't even open the Task Manager because it stopped responding. I tried to reboot the server, and it began installing Windows updates. I tried stopping the Trusted Installer service, but the updates didn't stop. After over 40 minutes, the server is back up, but it is still running extremely slowly. For example, it takes several minutes to open File Explorer

is this a dell server? Have you checked the OpenManage to see if there are any hardware issues?

Also Could it be related to their remote billers who use vpn to login to server? Check how many users are in session currently

Tech A 2024-10-15 16:44

server admin has been loading for +10 min

Tech A 2024-10-15 16:44

because of the network usage? I ran a speed test, all good

Tech B 2024-10-15 16:45

no, the server resources

Tech A 2024-10-15 16:45

cpu 5% ram 10% I cant see the drive usage

Tech A 2024-10-15 16:49

checking idrac

By the way, cpu was running at 5% but the clock was at 0.14Ghz causing the slowness. We kept trying stuff but it somehow got resolved by itself went back to 2.4Ghz

# Resolve Server Performance Issues with Low CPU Clock Speed

## Problem
A client office experienced severe server performance issues with Dentrix running slowly and basic system operations like opening File Explorer taking several minutes. The server had recently completed Windows updates after a reboot. Initial resource monitoring showed normal CPU utilization (5%) and RAM usage (10%), but the system remained extremely unresponsive. Task Manager would not open and Server Admin took over 10 minutes to load.

Further investigation revealed the root cause: despite showing 5% CPU utilization, the processor clock speed had dropped to 0.14 GHz instead of the normal 2.4 GHz, causing the severe performance degradation.

## Resolution
1. Check basic system resources (CPU percentage, RAM usage) to rule out obvious bottlenecks
2. Verify network connectivity is not the issue by running speed tests
3. Access Dell iDRAC or equivalent server management interface to check hardware status
4. Monitor CPU clock speed specifically, not just utilization percentage
5. If CPU clock speed is abnormally low (significantly below base frequency), check for:
   - Thermal throttling issues
   - Power management settings
   - Hardware faults in server management interface

In this case, the issue resolved itself automatically and the CPU clock speed returned to normal 2.4 GHz operation.
