Samsung netbook – brightness control

Came across this on the Samsung N210 Plus I bought for a trip coming up. Did the usual updates, patching, etc and the brightness control stopped working. Came across various articles and forum threads saying that it was the Samsung Easy Display Manager software and to reinstall it.

Well that didn’t help at all. What did help was installing an older version of the Intel graphics drivers. A big thanks to ArdeX of the SammyNetbook forums for posting that info.

DcDiag crashes when running tests

I’d not seen this one before, so figured it was worth noting for the future.

When performing an AD healthcheck, I tend to run the DcDiag tool like so:

dcdiag /e /c /v /f:dcdiag.log

This tests all servers in the enterprise (e), does comprehensive tests (c), produces verbose output (v), and logs to a file.

However, my dcdiag.log was getting cut off before it even got to the DNS tests – they ended up 21k in size where 100k+ is normal. Running it without logging to file showed it was crashing and events were getting logged. Doing a plain “dcdiag” it would run OK. This was on a pretty plain Windows Server 2003 domain controller.

The events logged were fairly generic 1000 ones, along the lines of:

Faulting application dcdiag.exe, version 5.2.3790.1830,
faulting module msvcrt.dll, version 7.0.3790.3959, 
fault address 0x00038efa.

Thankfully I had internet access and with some googling, I came across this blog post from Tim Bolton, which described the issue.

The culprit is a SP1 version of DcDiag, on a server upgraded to SP2. Once the correct version of the Support Tools was downloaded and installed, it ran just fine.
