Decommissioning a Small Business Server 2011 Standard without Exchange


Scenario: Client has their Emails hosted on Office365, applications on a new server, and new server is setup with DHCP/DNS/File Services. In the environment exists a Windows Small Business Server 2011 Standard server with FSMO roles, and the new 2019 Server. At the end of these steps, we should be able completely off this SBS server, and on our new Windows Server 2019 server. DNS on both servers are pointed at each other, meaning server A has server B as primary, and server B has server A as DNS primary.

Transition Process:

1. Run DC Diag to discover any possible errors or issues.
I ran into this error, but event logs ended up saying these completed after these errors showed up.


2. Transfer FSMO Roles

3. Performed these steps SBS-DECOM and DNS cleanup.

Watchguard HTTP Invalid Request-Line Format Error

Image
My brother in-law was having some issues connecting his Playstation 4 to Grand Theft Auto V's online servers. The resolution was to create an Packet Filter for port 80 From my Trusted network to the IP address of the server IP shown as 192.168.200.1. It is an example only, and may be different to your setup. In the example below, 10.0.1.2 is the PS4. The rule was also placed above the HTTP proxy. Example Only: D eny 1-Trusted 0-External tcp 10.0.1.2 192.162.200.1 52668 80 msg="ProxyDeny: HTTP Invalid Request-Line Format" proxy_act="HTTP-Client.5" line="e\x04\x04" (HTTP-proxy-00) Per WatchGuard Knowledge Base ( Article ID :000007959) , This has to be done, because The PS4 Rockstar servers are using an invalid HTTP Requests over Port 80 that does not abide by RFC Standards for the HTTP Protocol.
