Sometimes in testing network settings and authentication ( for instance when setting up a Samba server and users on a CentOS, Ubuntu, or Feroda Linux system) I often find it useful to force my Windows PC client to “forget” the login username and password that it has on record, for the current session, so that I may login again with another username/password combo. Easily accomplished, this Windows trick works on all modern Microsoft operating systems.

The situation: You need to login again to a network share on a Windows file server, or a Linux server,  without rebooting the client computer.

The fix: Disconnect from the shares using the NET command.

1. Open a command prompt. (My favorite way is: Win-R, type cmd, press Enter)
2. Type NET USE * /DELETE
3. It will prompt you for verification, type Y and Enter.

That’s it! Enjoy, and may your login be forgotten!

The following is totally copied from myfixes.com excellent article.

This article applies to the following type of errors:

Resolution:

A. Boot the system into the Recovery Console and CHKDSK

B. Perform the System Restore
Inside the Recovery Console type the following commands to change the directory to the system restore directory:

If you get an Access Denied error:click here
If you don’t get an Access Denied error :

If there is no _resto~1 folder or if there are no restore points inside it:click here

If the _resto~1 folder exists, inside it there are several folders named RP1, RP2. These are restore points. RP1 is the oldest restore point. You can use

to view what RP folders are available. If no restore points are available click here. Otherwise choose the most convenient RP folder. Supposing we have RP3 available let’s type in:

Change the directory to snapshot:

Restore the main registry branches. If you are being asked if you want to overwrite type in y to agree.

Type exit to reboot the system. Start the computer normally

From Linuxquestions.org:

“There are probably several methods, but one is to use find to produce a list of all files (not directories) and then execute chmod on each of them. For example

find /my/directory -type f -exec chmod 644 '{}' +

Change the red parts to fit your needs. If you wonder what that ‘{}’ is..well, you may have guessed that it’s where the filelist is being put when exec’ing the given command on each file.

You can also first try the command without chmod’ing to see that it affects the right files:

find /my/directory -type f

The above would find all regular files (not directories, for example) from within /my/directory.

If the command happens to throw you an error about the exec part, chances are it’s because of the plus sign (+) that ends the exec part. In this case try replacing the plus (+) with an escaped semicolon (\;) so it becomes

find /my/directory -type f -exec chmod 644 '{}' \;

On some machines I remember that it worked with semicolon (which needs a backslash in front of it, to protect it from being interpreted by your shell), but on my current installation it’s the plus sign (without a backslash).

Another way would probably be to list all regular files on the directory (using either find or any tool that can just list all files without directories) and then pipe the output to xargs with which the chmod was run.”

find . -type d -exec chmod 755 {} \;

This will recursively search your directory tree (starting at dir ‘dot’) and chmod 755 all directories only.

Similarly, the following will chmod all files only (and ignore the directories):

find . -type f -exec chmod 644 {} \;

Assuming you are using Windows XP or Vista, you can use the DISKPART utility to delete these OEM partitions from DELL and other hard drives.

If you have data anywhere on the drive that you will be deleting the EISA partition from, backup that data now.

1. Connect the drive to the computer. If it is an IDE drive then do this with a USB-to-IDE device, or connect the drive directly to the IDE cable. If ti is a SATA drive then do this with a USB-to-SATA device, or connect the drive direclty to the SATA controller on the motherboard. In essence, the drive must be connected to the PC and it must be “seen” by the operating system.
2. XP: Start a command prompt in XP by going START > RUN > type CMD <ENTER>
   Vista: Start a command prompt in Vista by going START > type CMD <ENTER> in the “Start Search” box.
3. In the command prompt type DISKPART <ENTER>. This starts up the DISKPART utility.
4. Type LIST DISK <ENTER>. This shows the all the disks connected to the computer. Decide which one is the one you are wanting to delete the EISA / OEM partition from, and make note of which number it is.
5. Type SELECT DISK n <ENTER> (where n = the number of the disk you noted in step 4)
6. Type LIST PART <ENTER>. This shows the all the partitions contained in the drive you are working with. Decide which one is the one you are wanting to delete, and make note of which number it is.
7. Type SELECT PART n <ENTER> (where n = the number of the partition you noted in step 6)
8. Type DELETE PART OVERRIDE <ENTER>. This deletes the partition you selected.
9. You are done with deleting the partition. If you want to, you may now EXTEND another adjacent partition into that free space you just created.

Enjoy!
