Some startup problems may occur early in the startup process. In this scenario, Windows may not save the boot log file to the hard disk. Device Manager displays a graphical view of the hardware that is installed on your computer. Use this tool to resolve any possible device conflicts or to identify incompatible devices that may be the cause of the startup problem.
The devices that are installed on your computer are listed in the right pane. If a symbol is displayed next to a device, there may be a problem with the device. For example, a black exclamation point! Investigate possible device conflicts.
To do so, double-click the device in the right pane, and then select the Resources tab. Note the Use automatic settings check box. If Windows successfully detects a device, this check box is selected, and the device functions correctly. However, if the resource settings are based on Basic Configuration n where n is any number from 0 to 9 , you may have to change the configuration. To do so, either select a different basic configuration from the list or manually change the resource settings.
Incorrect changes to the BIOS of the computer can result in serious problems. Change the computer's CMOS settings at your own risk. If Windows can't resolve a resource conflict, verify that the computer is configured to allow Windows to enumerate the devices in the computer. To change the computer's BIOS settings, see the computer documentation or contact your computer manufacturer. If the computer starts correctly, the device that you disabled may be the cause of the startup problem.
For more information about how to configure devices in Device Manager, see How to use Device Manager to configure devices in Windows Server System Configuration Utility Msconfig. You can use this tool to change the system configuration and troubleshoot the problem by using a process-of-elimination method. You must be logged on as Administrator or as a member of the administrative groups to use System Configuration Utility.
If your computer is connected to a network, network policy settings may prevent you from using the utility. As a security best practice, consider using the Run as command to perform these procedures.
We recommend that you don't use System Configuration Utility to modify the Boot. To test the software loading process, make sure that the Load Startup Items check box is selected, and then select OK. Clear all the check boxes under Selective Startup. INI check box. Repeat this process and select each check box one at a time.
Restart your computer every time. Repeat the process until the problem occurs. When the problem occurs, select the tab that corresponds to the selected file. For example, if the problem occurs after you select the Win. The Startup tab lists items that load at startup from the Startup group, Win.
To isolate problems by using the Startup tab, follow these steps. To start troubleshooting, select the first check box, select OK, and then restart the computer when you're prompted. Repeat steps 5 through 8 for each service until the problem occurs.
When the problem occurs, you'll know that the last service that you turned on is causing the problem. Note this service, and then go to step Select Enable All, the check box next to the faulty service, clear the check boxes of any other services that you noted in step 3, select OK, and then restart your computer.
As a workaround, you can leave the faulty service turned off not selected. Contact the manufacturer of the faulty service for more assistance. You may be able to determine more quickly which service is causing the problem by testing the services in groups. Divide the services into two groups by selecting the check boxes of the first group, and then clearing the check boxes of the second group. Restart your computer, and then test for the problem.
If the problem occurs, the faulty service is in the first group. If the problem doesn't occur, the faulty service is in the second group. Sorry this didn't help. Thanks for your feedback. And the person with the issue claimed that it works, so try that first.

I can't see the sharing tab within any drive or folder properties on Windows I've looked here:. However, there's no option to disable simple sharing in the Folder options and the services they recommend starting Computer Browser, Network Connections, Server, and Workstation don't do the trick.
Any ideas? I found this helpful blog article, that describes the solution of crizCraig:. And for me it was also necessery to restart the explorer.

Collectives on Stack Overflow. You may have to remove old socket or state files first if you are changing to this security scheme from an older version. The drivers will create new files with the right owners and modes.
You may have to change the groups of upsd. These files should not be owned by nutsrv, since someone could compromise the daemon and change the config files. Instead, put nutsrv in a group "nut" in this example , then make the files owned by root. See security. The point is limiting your losses. If someone should happen to break into upsd in that environment, they should only gain access to that one user account.
Direct access to the serial device is not possible, since that is owned by another user. There is also the possibility of running the drivers and upsd in a chroot jail.
See the chroot. Put it this way - I wrote good chunks of this stuff, and I still run the programs this way locally.
You should definitely consider using this technique. Assuming you have a good reason for it see the next entry , then look at scheduling. This is by design. Nearly every UPS supports the notion of detecting the low battery all by itself. When the voltage drops below a certain point, it will let you know about it.
If your system has a really complicated shutdown procedure, you might need to shut down before the UPS raises the low battery flag. For most users, however, the default behavior is adequate. Ask yourself this: why buy a nice big UPS with the matching battery and corresponding runtime and then shutdown early?
If you purposely shut down early, you guarantee an interruption in service by bringing down the box. See upssched. Those programs need to see a host in your hosts. If your hosts. If you run your web server in a chroot jail, make sure the programs can still read hosts. You may have to copy it into the jail for this to work.
See the upsd. If you send the signals yourself instead of using -c, be sure you hit the right process. There are usually two upsmons, and you should only send signals to one of them. To be safe, read the pid file. Refer to the driver-name 8 manpage for more information. On Linux, udev rules are provided to set the correct permissions on device file.
Operation not permitted is a message pointing to a privilege issue. The most frequent issue is that udev has not actually applied the rule:. There was a mistake in the naming of the NUT udev rules file which resulted in the rules being overridden by another udev configuration file. While this has been fixed in the Git master branch, your distribution may still be affected.
On Linux, if two copies of a driver are competing for the UPS, these messages will appear in dmesg:. This can be a symptom of a source install conflicting with a package install. There is a rudimentary locking mechanism in NUT, but there is a chance that the packages might not use the same directory as the NUT default, and the conflict will be reported by the kernel.
This means all packages have been built by a third party. By default, upsmon runs most of the grunt work as an unprivileged user and keeps a stub process around with root powers that can only shut down the system when necessary. This should make it much harder to gain root in the event a hole is ever discovered in upsmon. If this really bothers you and you like running lots of code as root, start upsmon with -p and it will go back to being one big process. Get the latest stable release, and see if it still happens.
If it goes away, it means someone else reported it and got it fixed a long time ago. You may want to search the mailing lists to see if someone else has experienced the same problem. If so, there is a good chance that someone else has worked through the process necessary to shoehorn the latest NUT version into your distribution potentially with unofficial packages.
If your hardware is newer than the NUT release, there is a good chance that support has not been added yet. Please do not tell us you have the "latest version for Distro XYZ" - even if the developers are familiar with that distribution, it helps others if you quote the exact package version. If you are not actively developing a driver, can you use a snapshot instead?
The NUT instance of Buildbot generates tar files of the latest NUT source after each successful build, and these snapshots include a prebuilt version of the. The fix is to make them overlap - turn an owner into a developer or vice-versa.
