After that the changing environment variables get various issues which cannot find %windir%\system32\rundll32.exe errors

After you sort a few UAC problems on the computer of a friend (see http://answers.microsoft.com/en-us/windows/forum/windows_7-security/a-domain-user-in-the-local-administrators-group/745fc28d-7573-4414-aa4e-657054fc62dd) we hit another problem.

After modification of the environment variables, it seems that windows loses some environment variables until a disconnection/connection is made. If you open a back command prompt and type the value, there are far fewer variables and things like %windir%\System32 disappeared. If you try to open the variable dialog environment again, you get a 'cannot find windir%\system32\rundll32.exe %. The same thing happens if you restart in safe mode. After a closed session/login, added environment variable are there, so they are saved, it just seems like it won't let windows none of them until a new logon.

One oddity is that the variable env pathext has different things in after things go wrong. He started as a

PATHEXT = .COM; EXE;. BEATS;. CMD;. VBS;. VBE;. JS;. JSE;. WSF;. WSH;. MSC. ; PY

and after adding a new use env variable and opening a new prompt back, together said

PATHEXT = .COM; EXE;. BEATS;. CMD;. VBS;. JS;. WS;. MSC

Is this a sign of a register messed up, that could have caused the original problem, or something else? Any ideas on how to diagnose this problem? Any help much appreciated. I have left this in the Security section, as it seems that it could be linked to the original problem, but am happy to move.

Any help much appreciated.

I don't know what caused your problem, but your original path certainly seemed excessively long. There is a lot of overlap in it you need to remove - see below. In addition, having records of remote machines at the beginning of your path will cause the machine to slow down a lot. You should remove them.

  • Windows 7 fail to recognize new password after that the user changes

    Hi, I have this weird problem, until now happening in Windows 7 machines in a domain Active Directory.

    A user who changes his password at any time before the expiration of the password and the message indicating that the change has succeeded appears as usual. However, after the closure of the current session, disconnection and/or same as restarting the computer where the user has changed the password, he or she is unable to connect with the new password, the computer will only accept the old password. Things don't stop there, if the same user tries to log on to another computer (where he worked before), he rejects the new password with the message "user or incorrect password" as well, but again only accepting the last password used in this second computer.

    A friend at work discovered (by pure chance) that run a MalwareBytes (hereinafter MB) scan and remove all detected items eliminate the problem, not immediately, but after a computer restart. I did the same thing with another user but took my time to browse the list of detection MB and I found that all detected items were related to domain policies legitimate registry keys.

    Things already checked:

    -Normal network connectivity.

    -Not all computers are affected.

    -All affected computers are running Windows 7 Pro x 64.

    -Users who have never used the affected computers can connect without a problem.

    -Users who are unable to connect the affected computers can connect to other computers, they have ever used without problem.

    -Computers have been restarted before using MB, but the problem persists.

    -Checked the names of registry keys, but could not find one related to the connection of the user.

    So my questions are, why this computers only validate against the local SAM? What other things can check to validate what happens?

    Thank you.

    The only way to install an ipad app is through the app store.  PC or Mac software does not run on the ipad.  Search in the contacts link at the bottom right of this page.  Give apple a call.

    I guess is the icon for pages in icloud for storing documents pages.  At the same time, apple had a cloud based pages.  Not sure what happened to her.

  • After that I changed the Duplex parameter on NIC's Service console, I am not able to connect the ESX host

    Hi all

    Please help solve my problem.

    After that I changed the Duplex parameter on NIC's Service console, I am unable to connect the ESX host. How can I reset the 100 MB NETWORK card duplex. Can someone help me please.

    Concerning

    Vijay

    Hello

    As the bulb you have two problems that are not related.

    (1) duplex setting, your switch and NIC must match. If one is assigned to auto-negotiation, then the other must be set to auto-negotiation. Personally, I tend to let auto-negotiation unless there is an absolute reason to spend. If you then turn on the both sides of the interface, the switch port and esxcfg-NICS allows you to change the duplex, etc.

    (2) passwords for root are not related to the network unless you have also run esxcfg-auth authentication remote.  The only time I saw what you have here is when the system is configured to try to authenticate remote and not locally.

    The two problems are fixable by booting into single-user mode, set the duplex and reset the password.

  • How the PATH environment variable longer?

    Hello

    I use Windows Vista Business.  Lately, I just installed the beta of Intel Parallel Studio and found that my path variable ran out of space.  Internet research concluded that there cannot be more than 1024?
    It is too little for me to welcome all directories program that I installed, and thus some programs no longer work correctly.
    I wonder if there-
    (a) is a way I can expand the size of the Path system variable?
    (b) add another variable which can take some Path variable values so that I do not violate the limitation of 1024.
    Thanks in advance!
    A

    Hello, Gutsingh

    The PATH environment variable has a fixed limit of 1023 characters can be used. It doesn't seem to be a way to extend this. Other environment variables have a higher limit, which can be useful.

  • When the Admin sign on the office comes to the top, but after that the computer does not respond when the user tries to do anything. There are actually turns off the computer with the power button.

    Original title: user profile

    My administrator user profile does not work properly, but I have a user profile that has activated the parental control that worked well for about a year and yesterday when this user logs on the desktop comes up, but after that the computer does not respond when that user tries to do anything. There are actually turns off the computer with the power button.  I ran a virus scan and spyware scan in my user admin profile and he has not found anything.  I don't know what to check.

    Hello rhunter15,

    There may be a program to interfere with Parental controls so that we can try a few things to see if we can determine the application or program that is causing problems.

    First of all, we run System File Checker to see if you have a corrupt file system.

    • Click Start
    • Click on all programs
    • Click Accessories, and then right-click on the command prompt.
    • Select the Security tab and choose "Run as Administrator"
    • Click on command prompt
    • Type SFC/scannow.

    It will scan and repair any damaged operating system files.

    To determine if there is a program because of a conflict, we recommend that you perform a "clean boot" of the computer. A clean boot is designed to disable programs and services in the background as much as possible. This helps determine which service or program can be the cause of the problem.  For more information about how to perform a clean boot for troubleshooting, click the number below to view the article in the Microsoft Knowledge Base.

    KB 929135 - how to solve a problem of performaing a clean boot in Windows Vista.
    http://support.Microsoft.com/kb/929135

    Once you have finished the clean boot, check again and see if you get the error of parental control.

    If please post again and let us know if that helped pinpoint the problem or if you still need help.
