solution for dsl on win 2k3?

[Tiffy]

im sorry if this post has already been posted up..but im really lost reading all the guides about tweaking speed...im kind of confused..and i have not found any guides for win 2k3(i thought tweaking of speed has to depends on the OS you're using?)

i did a tcp/ip check as on SG site and this is the result.
==================
SpeedGuide.net TCP/IP Analyzer
TCP properties for IP = *********()
Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.1.4322)
Notes: Read the Analyzer FAQ if the above is not your IP address.

TCP options string = 020405a00103030201010402
MTU = 1480
MTU is optimized for Windows XP PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.
MSS = 1440
MSS is optimized for Windows XP PPPoE DSL broadband. If not, consider raising MTU to 1500 for maximum throughput.

Default Receive Window (RWIN) = 257760
RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
Unscaled Receive Window = 64440

RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
506880 (MSS x 44 * scale factor of 8)
253440 (MSS x 44 * scale factor of 4)
126720 (MSS x 44 * scale factor of 2)
63360 (MSS x 44)
bandwidth * delay product:

Your RcvWindow limits you to: 10310.4 kbps (1288.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4124.16 kbps (515.52 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 46 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000

==================
my dsl seems slow..i have no idea but i feel that my download is always tap at 30-40kb altho this is a 512kb speed dsl plan (i know you can't get 512kb speed but 30kb is too slow?)
i've just download cablenuts but when i hit 'retrieve current registry settings' there's nothing..(maybe cablenuts is not compatible with win 2k3?) i didn't change anything bcuz i was afraid that i might not be able to restore back to the default(since i can't retrieve current registry setting and save it as a backup).

is there anything i can do to improve my speed a little better?
many thanks.

With windows 2003 you just follow the tweaks for xp
