Windows Server 2008 R2 firewall service will not start
paul | Monday, 15 October 2018 | Windows | 2008R2

We recently had an issue with some of our older Windows Server, running 2008 R2, not starting the firewall service. It failed with the error "The windows firewall service terminated with service-specific error 2150760483 (0x80320023)".


This was due to a group policy firewall exception which the 2008 R2 server did not like. Removing the policy and then running a Gpupdate/force fixed the issue.

PRTG SQL Sensor error
paul | Thursday, 13 September 2018 | PRTG | SQL

After recent windows update some PRTG SQL sensors have stopped working reporting the error "(Microsoft SQL DEPRECATED) Down  (The type initializer for 'System.Data.SqlClient.SqlConnection' threw an exception.)".

By removing the updates individually it was determined that the error was caused by KB4457035 "Update for Microsoft .NET Framework 4.6". Removing that update and rebooting the server resolved the issue.

Checking Office 365 for users auto forwarding their email
paul | Wednesday, 05 September 2018 | Office 365 | Exchange

In Exchange Online users can forward their emails automatically to another email address. If this is to a personal external email address then this may not be secure or against company email usage policy.

To check if any of your users are doing so you can run the following powershell command:

Get-Mailbox -results unlimited -filter {DeliverToMailboxAndForward -eq 'True'} | select UserPrincipalName,ForwardingSmtpAddress,DeliverToMailboxAndForward


Auto forwarding can be blocked in the Exchange Admin Center. Go to "mail flow -> remote domains" and configure domain unticking "Allow automatic forwarding" option.
