Hi all, I hope I'm posting in the correct forum - I just registered on here because I'm looking for the answer to a really specific question on MS DOS that I haven't been able to find anywhere online, figured you guys might be able to help.

The trick is that I need the command line:

Code: Select all

display [IP address here] DNS

to run the equivalent of a displaydns command

I also need the line:

Code: Select all

clear [IP address here] DNS

to clear the DNS cache, essentially the same as a flushdns command.

I know that this is kind of a weird request, but I was curious if it was possible. Anyone know if that's doable or how to do it?

EDIT: I worded the initial request wrong, so I edited it on here in hopes of clarifying it a bit.

I believe this should work for you

The command ipconfig /flushdns clears the DNS cache. All records up to this point in time are removed from the cache.


C:\Users\Martin>ipconfig /flushdns



To check to see if it did would be this

C:\Users\Martin>ipconfig /displaydns

Of couse substituting as needed the correct drive letter and user name

What I need is to create a custom command line so that the line "display [IP address here] DNS" shows the DNS cache and so that the command line "clear [IP address here] DNS" clears the DNS cache. I basically want the line:

Code: Select all

clear [IP address here] DNS

to do the equivalent of a flushdns command for the IP address being designated - all of this stuff will be internal, so it can operate the same way as a standard IP config for the most part. Does this make sense? I know it's a convoluted and kind of strange way of doing this, but it's a pretty specific task I'm trying to do.

1) create the executables (batch file is probably all you need here) that will do what you want

2) test

3) rename them into the command name you want (I wouldn't use the names of commands you're "replacing") (you cannot use any spaces in the name of your new command)

4) copy the executables into C:\WINDOWS\system32
