Re: Internet Speed

I think what we are trying to say is to use the DHCP from the SBS and NOT
the router. That way the client computers will get the correct info which is
DNS and WINS point to the SBS.

Thanks. In your directions you said: "Configure internal client
computers'
IP and DNS as dynamically". I thought the directions for initial set up,
and
most of the comments from these threads say to set all machines primary
DNS
as the server IP address. Am I mis-understanding your comment above? Are
you saying the server IP address should not be the primary DNS under
Internet
protocol (tcp/ip) properties---general tab---?

Hello Steve,

Thank you for posting here.

According to your description, I understand that the connection from
internal clients to Internet is very slow if you configure the clients'
DNS
pointing to SBS. If I have misunderstood the problem, please don't
hesitate
to let me know.

As you mentioned "We have a router connected directly to our switch", I
guess your SBS has single NIC, also connected directly to the switch, and
clients computers also connected directly to the switch. If I'm wrong,
please feel free to let me know.

First, it is recommend to configure all SBS client computers' IP and DNS
as
dynamically, make all clients get IP and DNS from SBS DHCP service.
Meanwhile, since we by default enable DHCP service on SBS, we have to
disable any other DHCP service in network, also have to disable DHCP on
router.

Based on my research, this is a DNS and DHCP issue, it has no
relationship
with WSUS. I suggest we try the following steps to see if we can resolve
this issue:

1. You have to rerun the CEICW to make sure your SBS 2003 server have
right
network configuration. Go through the follow KB and Rerun CEICW again
carefully.

How to configure Internet access in Windows Small Business Server 2003
http://support.microsoft.com/kb/825763/en-us

Detailed steps for your reference:
One network adapter - manual router connection to broadband
a. On the Connection Type page, click Broadband, and then click Next.
b. On the Broadband Connection page, under My server uses, click A local
router device with an IP address, and then click Next.
c. On the Router Connection page, next to Preferred DNS server and next
to
Alternate DNS server, type the IP addresses that are provided by your
ISP.
In the Local IP address of router box, type the IP address of the router
that the server uses to connect to the router.
d. Click to select the My server uses a single network connection for
both
Internet access and the local network check box, and then click Next.
e. A message may appear that warns that the firewall that is provided
cannot be configured. You are offered a chance to view information about
configuration settings for an existing firewall device.
f. On the Network Connection page, click Server Local Area Connection
under the Connection Name.
g. Click Next.
h. Complete the Configure E-mail and Internet Connection Wizard.

2. Configure internal client computers' IP and DNS as dynamically

Then, test the issue. If the issue persists, please go to the following
steps.

3. Configure DNS forwarders on SBS DNS service

a. Run dnsmgmt.msc command on SBS to open DNS management console

b. Right click the DNS server name, select properties

c. Select Forwarders tab, input your ISP's DNS IP address under Selected
domain's forwarder IP address list:

d. Click Add button to add the IP to the forwarders list

e. Click OK to finish, then, test.

If we cannot resolve the issue after we perform the above steps, please
kindly help me collect some information for further investigation:

1. Run command "ipconfig /all > c:\ipconfig_sbs.txt" and "route print >
c:\route_sbs.txt" on SBS, send the files c:\ipconfig_sbs.txt and
c:\route_sbs.txt to me at v-terliu@xxxxxxxxxxxxx

2. Run command "ipconfig /all > c:\ipconfig_client.txt" and "route print
>
c:\route_client.txt" on problematic client, send the files
c:\ipconfig_client.txt and c:\route_client.txt to me at
v-terliu@xxxxxxxxxxxxx

3. Please let me know your network topology

4. Please let me know your router's internal IP

Hope these steps will give you some help.

Thanks and have a nice day!

Best regards,

Terence Liu(MSFT)

| I don't know if this is all related, but I recently did my first WSUS
for
the
| server and loaded all security and critical patches. I wanted to get
the
| server done first, so I initially excluded all client workstations.
After
| two consecutive download and updates on the server, I temporarily
turned
off
| autosynch because I can't bring the server down during the week for
re-boot.
| The next thing that happened was the client workstations slowed down
| considerably because the svchost.exe was taking 300MB of memory.
(Seems
odd
| since I excluded them from the autosynch). From reading in this forum
I
know
| it has to do with WSUS on the workstations, so I temporarily turned the
auto
| update service off. The svchost.exe went back to normal and the
| workstations sped up, except for the Internet. It was considerably
slower.
|
| On my workstation only, I changed the DNS to find dynamically and my
| Internet speed went back to very fast. (We have a router connected
directly
| to our switch.) Is this coincidence, or is it related to WSUS in some
way?
| What would happen if I didn't hard code the DNS address of the server
into my
| network configuration? I imagine it would affect mail (although we
currently
| use POP3) and RWW, which we all use. Ultimately, I know I need to
figure
| out why the Internet is slow when the DNS address is set to point to
the
| server, but don't have any idea why.
