Brian R. Bondy's questions

I am on a Windows centric LAN without a domain.

I have access to several machines on my network, each with different username and passwords.
I originally connected to them with a UNC path in explorer and entered in the authentication information.

Now when I type in explorer I can access the machine without entering a username and password.

What I'm trying to do is get that prompt again without logging off. I know I can clear connections using:

net use * /delete

My connections are no longer listed now, but I can still go in explorer and access the shares without a username and password.

If I log off and back on the problem is fixed, I will be prompted again for the auth info. But logging off is inconvenient for me.

Is there a better way to clear the auth info so I will be prompted when trying to access an administrative UNC share?

I do notice that if I wait long enough I will eventually get the prompt again. Is there a way to eliminate this timeout though?

I'm trying to compare 2 versions of a backup software product. I setup all IO to go to a dedicated drive.

Is there a way with performance monitor (or anything else) to track the number of IO operations.

I know I can measure disk queue length and different stats like that, but I'd like to know the exact number of IO operations.

I have 2 folders, the first:

C:\folder1
C:\folder1\subfolder\a.txt
C:\folder1\subfolder\b.txt

and the second:

C:\folder2
C:\folder2\subfolder\a.txt

I would like to merge them like so:

C:\folder2
C:\folder2\subfolder\a.txt (folder 2's a.txt)
C:\folder2\subfolder\b.txt

Description of what I want:

Is there a simple DOS command to copy all of the folders, subfolders and files from folder1 TO folder2, but if something exists in folder2 I do not want to overwrite it. If folder 1 has files that do not exist in folder2, I want them to be copied in.

Note: both folder1 and folder2 share common subfolder names.

Note 2: Folder2 is several TB's so I really have to copy into folder 2. Folder1 is only several GB.

I can't do this in windows explorer because there is no option to say overwrite files? No to all.

I am logged in as administrator and I right click on a folder and then go to properties, then the security tab, then advanced, then the owner tab. I am not on a domain.

I see that the folder has a group ownership of administrators.
I change this ownership of this item and all subitems to the user administrator. I verified and all subitems do indeed now have the ownerhip of administrator.

But then I try to create a new txt file inside that folder, and when I go to see what the ownership is on it, it is administrators. I expected the new ownership to inherit the ownership from it's parent item or take it from me the logged on user administrator.

What can be done to solve this problem so that new files I create when logged on with administrator will create them with an owner of administrator instead of administrators?

Is there a free service for checking for common DNS errors on your domain? I previously used dnsstuff.com for this, but they since moved to a paid model.
