We’re having a problem opening this location in File Explorer. Add this web site to your Trusted Sites list and try again

If you see this message when you try to uload file to SharePoint or open library in Windows Explorer, check if you are using Windows 2012 R2 server. If it is the case, then most probably your server does not have Desktop Experience feature installed. It make sense as it is not required on the server. Anyway you can add it using Service Manager, you will need to reboot this server after that.

Skype for Business SCOM watchernode is not doing all tests

For syntetic tests in watcher we want to see all tests, but in one co nfiguration we see only 2-3 first test in Eventlog and that's it.   All manual tests are passing ok.

To debug we will run MainSTExecuter.ps1  (that's main script for watcher - it gets regenerated by SCOM agent and can be found in temp folders of monitoring agent on watcher). When we run the script (run as admin) we can see that it takes a lot of time to run each test due to error in autodiscovers HTTP. This port is closed, in favour of HTTPS. But for tests it is a big problem as timeouits gets accumulated and not enough time to run whole script inside 15 minutes.

We will disable this check

Set-CsWatcherNodeConfiguration -Identity "poo.fqdn" -UseAutoDiscovery $false

and now all tests are passing ok with no delays.

Direct access NLB does not work

I had a problem with HA DA, it was working on one server but not on the other one in NLB.

I checked few things until I discovered that "route print" on the client does not have a route to fd40:....   network - DNS64 subnet for internal network.


Then I discovered that in fact the same route was missing on the second server.

added a route in netsh interface ipv6 add route  IPv6 subnet and made it publish=yes.

If you have icons of agents State from Health Service Watcher greyed out in the view Monitoring-Operations Manager  - Agent Details - Agent Health state  you probably need to reset cache of Health service on the server - read this article first:
