WHS 2011 UR2 Computer Monitoring Error

Recommended Posts

Have you installed UR2 and getting an error popping up in your tray? You can go to Microsoft's Connect site and vote up the bug here.

 

Since the "Update Rollup for Windows Home Server 2011 (KB2630434)" I receive continuous alerts of "Computer Monitoring Error"

 

The response from MS is as follows:

 

This alert is caused by an internal error "Object reference not set to an instance of an object", we are investigating the root cause, a quick workaround is you could "Ignore" this alert, do not "Delete".

 

Best wishes,

Windows Home and Small Business Server Team

 

Vote it up if you see the error although MS will fix this one.

Has anyone been able to try this on a fresh WHS 2011 install? Is there still an issue?

 

Will try it on a fresh install on Hyper V tonight and let you know.

I tried going to the link but it took me to a "page not found". I went to the bugs page but couldn't find one regarding the WHS 2011 -- did they move it?

As of yet, I do not see the Monitoring Error on a Fresh Build (test), but it also has no clients connected to it either. The media retrieval error did show up.

There is new, potentially useful information on the wiki page for this, which you can get to if you click the help hyperlink from this error.

 

The crux of it is, there are multiple potential causes, but if it has happened since UR2, it is likely because one of your backups is unable to determine the OS of the machine it is backing up. It seems to have been caused by MS's attempt to correctly identify OS X versions; in fact they state it should only happen if you are trying to back up a Mac, but I got it even with all MS devices.

 

However, the good news was when I looked at all my backed-up clients properties AND (this is key) my two archived PCs, one of the archived PCs showed "unknown OS." I had to delete that PC from backup, thus losing the archive (which could be problematic since let's face it, the reason we archive the backup is because we probably don't have immediate access to the PC to backup on a normal basis) but it also removed the error.

 

Here is the wiki page:

http://social.techne...-launchpad.aspx

 

Excerpt:

“Computer Monitoring Error” shows on the Server after updated with Update Rollup 2.

This happened after the system installs Update Rollup 2

 

Cause

It is caused by one of the Alert evaluation components – ServicingAlerts.dll, when it tries to evaluate whether there are Mac clients in the network. It will throw an exception when some machine returns "unknown" for the OS version. It could happen when you have a machine that is disconnected from the server.

 

Workaround

1. Select any client computer in the “Computers and Backup” tab on the dashboard.

2. Check the “Operation System” value in the “General information about this computer” area on the bottom.

3. If the value is unknown, right click the client computer and select “Remove the computer”.

Note, If you see the clients are in the "Archived computer backups" category, please be aware that if you remove the computer, it will also remove all backups for that client.

Thanks for the clarification and detail. Potentially could be an easy fix if you locate the problem PC.

      Hi All,
      I have built a WHS 2011 server.  All was well except my Win 10 PC would not back up to it.  Installing the KB281721 hotfix was done on the server and part of the process was to reinstall the connector on the PC.  I uninstalled from control panel.  I then had a ton of problems connecting to WHS 2011 connect webpage.  This turned out to be being blocked by the server windows firewall, which started working ok when I disabled the private firewall.
      Now the connector web page comes up and initiates the install.  Connect a computer wizard starts up and asks me for the server name or IP.
      Neither work.  Whether I enter the server name or the IP it says the server could not be located.
      If I open the remote access web page from any device inside or outside LAN, I can connect to the server and carry out all you would expect.  I can connect via RDP, I can ping the LAN IP, I can ping the FQDN and WAN IP.
      The server is showing in Network and all shares are browse-able.
      I installed the find my server wizard and that failed to find it even using the command line switch with the <servername>
      So how do I get the server connector up and running.
      I have added theses ports to the router
      65510 
      3389  disabled at the moment until I can secure it better
      4125
      443
      80
      I found 3 copies of windows home server in the listed devices and have removed all of them.
       
      I am at a loss as to what to do next.  Hoping some experienced WHS 2011 server people know what to do next.......

      Hi, hoping for a bit of guidance on what todo with my N40L box.  I have it sat in the living room connected to the TV.  Its running Windows 10 with Kodi, sabnzb, torrents, and a bunch of discs with all my files and media.  I would like to have a solid setup that can be used to access my data,, share game ISOs, download NZBs, do backups, etc.
       
      I'm going with WHS 2011, is this the best option considering the other HS OS's available such XPEnology, FreeNas, etc? 
       
      Specs:
       
      N40L:
      8GB ATI GPU BIOS Hack 128GB SSD (OS sitting in DVD Bay) 1.5TB HD 200gb HD 200 gb HD2 I have a 750GB SSD - not sure what to use this for?  
      Thanks for your help!

      Hi folks,
       
      I have had my install of WHS2011 for some time and with a static IP have been able to use remote access by switching on that service albeit not using microsoft's domain name registration.
       
      The system has worked for about 5 years but is now grumbling about certificates when I login either remote or using one of my PCs on the local home network using mstsc.   The error message is attached.    Clearly if I click yes and ignore the error I can continue as I can when accessing the server using the static IP.  
       
      I have looked at various posts about certificates and buying certificates for domain names etc. most of which the responses go over my head.
       
      Any assistance that could help me address this would be gratefully received.
       
      Boogie.

      I have my WHS 2011 client PC database on its own dedicated drive. This drive is now showing errors, and the client pc backups are now not completing. I have a replacement drive and a backup of the client PC database made before the failure. How can I replace the client PC backup drive, restore the client PC database, AND have WHS 2011 continue to use the restored client PC database?

      I have a WHS 2011 box with no special networking-related settings going on. Accessing shares on all the PCs in my house get around 100MB/s read and write. All macs are getting around 25MB/s.  Tried mounting shared volumes as cifs and smb.  I've found a few forums of people reporting the same with various forms of windows servers and though there are 100 hack-y suggestions, nothing has ever worked for me.
       
      Anyone have any ideas on what I could do to improve performance? If i can't get this working well, it'll mean a lot of buying decisions, completely reworking my network storage.
