Tangible Thoughts SharePoint, MOSS? and all the other questions

Faced a dilemna with a SharePoint box recently.

This SharePoint box had been running for over 4 months, and had over 500 users using it daily.

Its not a dedicated server box, but more of a PC that runs as a server. Its local HDD capacity is 40 Gigs split up into 2 20GB Partitions. Most you might think that is OK (I innittially thought - what the heck, its just WSS hosting 1 site).

But remember 500+ users on a daily basis. IIS Logging was turned on (default settings + few other properties for a usage tracking application used internally). Eventually within the 4 months of operations the IIS logs grew up to consume all the space of the local partition.

Trying to log on to the local machine to correct the issue generated several logon errors, including one that said unable to load local profile, and then every subsequent screen was black. The entire desktop was black (almost as if if the video card had failed). You couldnt even read any of the error/warning dialogs that would pop up. Fortunately we were able to load the command prompt, move the logs and sort out the screen blackness issue.

But even after that the Windows logon screen continued to be all black. Which was very strange. We were almost contemplating an OS re-installation fearing a corrupt OS.

but fortunately we ran across this newsgroup posting which saved me a whole load of trouble.

Excelent tip. Thanks for posting. Always watch for those runaway log files or this one will burn you too.

Here is the fix: http://support.microsoft.com/default.aspx?scid=kb;en-us;906510

We had this issue after the C: drive ran out of space so, I am guessing it happens when it can't fully load the registry either to a swap file or to a the TEMP directory if it does that. In eiter case, it's a simple fix. I haven't read the post above's link but just ran across this when looking for the fix.

Thanks, you saved my life. Never would have thought the colour scheme would have done this to me.

Cheers

k, fearing that the newsgroup posting might get lost, I think its a good idea to reproduce it here

"saw this solution in another post:

The color schemes in the computer's default profile may have been set to
black for every scheme element. Please review the below steps for this may
resolve your issue:
On the Windows 2003 Server this can be verified by navigating to the
following registry key:


HKEY_USERS\.DEFAULT\Control Panel\Colors
If this is the issue all colors scheme element registry values will be set
to 0. Compare this with a known good copy below:


[HKEY_USERS\.DEFAULT\Control Panel\Colors]
"ActiveBorder"="212 208 200"
"ActiveTitle"="0 84 227"
"AppWorkSpace"="128 128 128"
"Background"="0 78 152"
"ButtonAlternateFace"="181 181 181"
"ButtonDkShadow"="113 111 100"
"ButtonFace"="236 233 216"
"ButtonHilight"="255 255 255"
"ButtonLight"="241 239 226"
"ButtonShadow"="172 168 153"
"ButtonText"="0 0 0"
"GradientActiveTitle"="61 149 255"
"GradientInactiveTitle"="157 185 235"
"GrayText"="172 168 153"
"Hilight"="49 106 197"
"HilightText"="255 255 255"
"HotTrackingColor"="0 0 128"
"InactiveBorder"="212 208 200"
"InactiveTitle"="122 150 223"
"InactiveTitleText"="216 228 248"
"InfoText"="0 0 0"
"InfoWindow"="255 255 225"
"Menu"="255 255 255"
"MenuText"="0 0 0"
"Scrollbar"="212 208 200"
"TitleText"="255 255 255"
"Window"="255 255 255"
"WindowFrame"="0 0 0"
"WindowText"="0 0 0"
"MenuHilight"="49 106 197"
"MenuBar"="236 233 216"


There is two ways to fix this problem:


1. Export the registry key from a known good machine into a .REG file.
Import the .REG file into the new machine.


2. You can also construct/copy-paste the following information into a text
file and give it a file name with a .REG extension.

Hi, I have the same problem above my HDD was full and then I rebooted after freeing around 5GB but this black logon window is on and I can't seem to login I probably messed up one of the fields! and finally I tried a login thing but the windows attempts to login then gives an error which I can't read ofcourse! Any work around this before the login screen?? I tried all F8 modes with no luck so far!!

AJ,

Apply the registry changes from another machine.

Open Regedit, then go to File -> Connect Network Registry.

I tried this and it was still showing the black screen on all logins.

I then changed the color settings in

CurrentUser>Control panel>Colors.

I had to to this by using command line as you cannot view the current user location remotely.

Then wrote a bat file to run the registry file and put it in the all users>startup folder.

When a user logs in the bat file will run, then the user must log off and log back in. Screen = normal

I had the same problem. I went with Todd Heron's first solution and it worked. I'm still wondering how all the control panel colors got set to 0 in the first place, but at least it's fixed now. Thanks!

Excellent job on Todd's part. Resolved my issue as well. I think mine was also related to the hard drive filling up and default profiles not running correctly.

Excellent post Todd! More than 2 years later, it has helped resolve the problem. It initially seemed to've been caused my malware, but I believe the hard disk had filled up as well and caused the issue.

For those who can't access the registry remotely, you can Google on how to do this. You can connect to remote computer through Computer Management, ensure Remote Registry service is enabled, and then open registry on a local computer and select "Connect Network Registry or something."

Why The logon screen turns black after you press CTRL+ALT+DELETE to log on to a Microsoft Windows Server 2003-based computer
?
Virus or Worm ?
