Exchange 2019 - missing dll file from C:\Windows\System32\inetsrv

We run a single on-premises Exchange 2019 server at our office. Our sitewide antivirus system deleted from this server the following file as it identified it as bring a virus:

C:\Windows\system32\inetsrv\SrvGlbHttpModuleEx.dll

Now we cannot connect locally to serer via Exchange Management Shell or Exchange Admin Console. Lots of errors showing is Event Viewer regarding missing SrvGlbHttpModuleEx.dll

Is there any way to recover this file from say Exchange install media, etc without having to totally rebuild the server?

Solved my own issue. The dll file the anti-virus progam did delete was 100% a virus.

However the “applicationHost.config” file located under “C:\Windows\System32\inetsrv\config” still had reference to that dll under Global Modules. I deleted that line, restarted server and now Exchange Management Shell or Exchange Admin Console accessible.
