Windows 2003 join SBS 2003

I am trying to have Windows 2003 Enterprise to join SBS
2003 Premium.
Box boxes have 2 Nics. I am disabling the other one in
order to connect.
I created the server in the SBS box, then in W2003 went
to the url and clicked connect to network.
I was able to enter the username/password info, then it
retrieved the list of Servers I added this server. Then
when it was trying to configure the network gave and
error.
That says:
An error ocurred when configuring networking settings.
please your Network Administrator.

Hi Jose,

Thanks for your posting here.

Please try the following suggestion.

Ensure you are using Domain Administrator to log on to the client computer.

II. IE security setting

1) In IE, go to Tools, Internet Options, Security.
2) Highlight Trusted Sites then click the Sites button
3) Add http://*.domain.local
4) Exit the wizard and re-launch it from:
http://servername/ConnectComputer, does the problem still occur?

III. GP settings

1. In the Domain Controller Security policy on the server, expand Local
Policies.
2. Click on Security Options and set Network Security: LAN Manager
Authentication to "Send LM and NTLM - use NTLMv2 session security if
negotiated." Click OK to make the change.

3. Run gpudate /force at a command prompt.
4. Start | Run, type "regedt32". Go to the following key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\lanmanserver\parameters

Make sure the following values are set :
Enablesecuritysignature = 1
requiresecuritysignature = 0

5. Next, go to the following key:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Contro l\Lsa

Set the following value:

Incompatibility level = 2

6. On the client machines go to the following keys and make sure the
following values are set correctly:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Contro l\Lsa

restrictanonymoussam [REG_DWORD] = 0x1

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\lanmanworkstation\param
eters

enablesecuritysignature [REG_DWORD] = 0x1
requiresecuritysignature [REG_DWORD] = 0x0

7. On the client go to Start | Programs | Administrative Tools | Local
Security Policy.
8. Expand Local Policies and click on Security Options. Check the
setting for the following three options:

Domain member: Digitally encrypt or sign secure channel data (always) set
to enabled
Domain member: Digitally encrypt secure channel data (when possible) set
to enabled
Domain member: Digitally sign secure channel data (when possible) set to
enabled

9. Reboot the workstation/member server.
10. Join the domain.

If the problem still persists, I would like to suggest that you post your
questions to the following news groups:
