I read a previous posting that refers to comcfg and dfs$. (what are COMCFG and DFS$ shares?) I tried to enable te group policy setting above and have the entry be "blank". I have gone back in and it is listing comcfg. So I look at the installation. There's no biztalk or dfs. What is the proper way to remove this, or make it appear blank in the gp entry? Do I remove the registry entry(nullsessionshares) or blank that entry out(leave the entry nullsessionshares) from hklm\system\currentcontrolset\services\LanmanServer\Parameters?

So I implemented this change, and I still see comcfg in the registry key you mentioned above. nullsessionshares has a REG_MUTLI_SZ=COMCFG. I also see "comcfg: in rsop results. For stigs, I'm supposed to enable this and have it be blank. I saw your screen shot, but my computers show comcfg even if I blank them out, go back in, its there. Is that a new default that cannot be removed for some sort of functionality?

Hi, However, it's safety to keep COMCFG in this policy or you need to set another value to override the default value like 135$. RegardsRick Tan TechNet Community Support
