Impact to KEPServerEX 5.18 from Microsoft DCOM enhanced security (KB5004442)

[AS_10412322]

Hi, I see this applies to 

• KEPServerEX 5.20.396.0 to 6.12

What about the older version like 5.18? Any suggestions please? I cannot find any documentation from PTC.

Hello,

We only code Kepware knowledge base articles back to version 5.20, but I can confirm the steps in this particular article (Article - CS350729 - Unable to establish OPC DA communication after installing Microsoft DCOM Hardening patches (CVE-2021-26414) with PTC Kepware Products) are the same for KEPServerEX version 5.18. 

BRgds,
