14 DAY TRIAL // Microsoft has confirmed that its latest optional cumulative update is resolving a glitch causing trouble on Windows Server where RRAS is enabled.
All Windows Server versions are affected, beginning with Windows Server 2008 SP2 and ending with the latest Windows Server 2022.
Microsoft says the glitch was introduced by an earlier cumulative update, but it’s now preparing another update to resolve the whole thing.
“After installing KB5014678, Windows Servers which are using the Routing and Remote Access Service (RRAS) might be unable to correctly direct internet traffic. Devices which connect to the server might fail to connect to the internet, and servers can lose connection to the internet after a client device connects,” the software giant explains.
The company further explains that the latest Windows Server cumulative update, which was published on June 23 as an optional release, comes with a fix for this bug.
Automatic updates coming on July 12
However, the automatic update that includes the patch would go live in July as part of next month’s Patch Tuesday cycle that will also include security fixes.
“This issue is resolved in the latest Windows security update. If it's not possible to install the latest Windows updates on an affected server, the issue can be avoided by temporarily disabling the NAT feature on the RRAS server. For steps and guidance on this, note the ability to uncheck the "Enable NAT on this interface" option described on step 7 of the article Enable and Configure NAT,” the company explains.
For now, however, server admins are being told to keep their devices up-to-date, and if necessary, to install the latest optional update to get the fix right now. If they don’t do this today, the fix will be included in the next automatic update rollout that will take place on July 12.
