Windows 7 and network shares on W2K (Windows 2000)

So, I have an old Windows 2000 machine, it works, and I don't want to replace it.
The data it manages I share on the network through a normal shared folder.

No problems until Windows 7... Suddenly I can't access the share - invalid username/password is the error. It worked this morning but now it doesn't and nothing has changed...

Google informs me that the authentication used by Windows 7 now requires NTLMV2 and proceeds to tell me how to configure W7 to accept NTLM - except I have "Home Premium" on this machine and can't edit security policies (I thought I just couldn't use remote desktop connection to the machine, but we learn something new every day)...

There is, however, a registry key that can be changed or created:

[HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\CONTROL\LSA]

"LMCOMPATIBILITYLEVEL"=DWORD:00000001

Create (as I did) this key and give it a value of 1

Or, if it is already there, change the value to 1

The values defined for this key are:

Level 0 - Send LM response and NTLM response; never use NTLMv2
Level 1 - Use NTLMv2 session security if negotiated
Level 2 - Send NTLM response only
Level 3 - Send NTLMv2 response only
Level 4 - DC refuses LM responses
Level 5 - DC refuses LM and NTLM responses (accepts only NTLMv2)

Why S5397?

I need a fast system with lots of memory.
Dual quad core for maximum performance.
64GB of RAM, or more when I can afford it.

Well, it certainly looks like the TYAN Tempest i5400PW S5387 would work.

Others in the series also look acceptable, but this one has 1600MHz FSB and therefore supports FBDIMM 800 memory = More Bandwidth for all those gigs of RAM. The Block diagram in the data sheet for the 5400 MCH shows 17-21GB/s for (533-667) rated FBDIMM so I should get even better with the 800's...

A closer look at the "Seaburg" (5400) Memory controller shows two branches with two channels of four FBDIMM each for a total of sixteen slots. 4GB FBDIMMs are around $360 each, going to 8GB would cost $1,700 each - not sensible. So I could get 64GB on this system - but let's start with 32GB.

I need a suitable processor - 4 cores and 1600 Mhz FSB - the Xeon E5482 at 3.2GHz looks about right.

For video - NVIDIA 9800X2 looks interesting - two processors with 1GB of DDR3, not bad. XFX GeForce 9800 GX2 PVT98UZHDU is the part number.

Power supply - 860 W should be ample and PC Power & Cooling lists the S5397 as supported by the PPCT860.

Case - Thermaltake VG4000SWA - not only big enough but also has a clear side so that the POST codes on the motherboard can be seen.

Screen - Dell 2208WFP widescreen (1600x1050)

Keyboard - Logitech Bluetooth - Cordless Desktop MX 5000 (boy was that a mistake).

Everything is in stock at Newegg - my favorite place to shop (and no more New York sales tax - I'm always for that).

--------------------------

Issues - FBDIMMs run HOT!!! With 8 of the 800's in the system they overheat and the system will BSOD...

Unfortunately Crucial didn't know about it, so they graciously swapped out all 8 of them for me. I finally found the issue running Everest which will show the DIMM temperatures. Added some fans to the memory slots (Corsair Dominators) and fixed that problem....

The other issue still hasn't been resolved - the system will not POST with an XFX GeForce 9800 GX2 graphics card - so I have to use the single GPU version (which does work OK).

Murphy's Law

So, I created this blog to document my adventures with Tyan's S5397 motherboard.

Google immediately flagged it as a "spam blog".

So now I have to wait for it to be reviewed and unlocked...

Meanwhile stay tuned to my adventures in Tyan - land.
