Hey there,

Issue: We have XP PRO machines that lose connectivity to:

1. Mapped Drives (not able to browse mapped drives or use applications that are mapped)
2. Printers (not able to print or add printer)

These machines are on a domain.
Domain: Windows 2000 Server

When you reboot, everything is comes back and is functional...

Has anyone has seen anything like this??

Thanks for your Time!!!

How many machines are in the domain?

How many machines lose connectivity? How many segments? Routers? Hubs? Switches?

Describe the connection (including distance) from server to PCs

How many domain controllers? How many DHCP servers? Do they have the same scope, or different scopes?

Max: 25 machines on at one time...

Only the XP machines lose connectvity...

100 feet from farthest XP machine to router...

2 domain controllers PDC and BDC...

No DHCP servers...

[poopypants]

oops!

3 switches total before router...

[gerryf]

are these statically assigned ip addresses?

Are all windows XP machines on the same segment? Or different segments?

[poopypants]

YES and Same Segment...

[poopypants]

can you define segment for me?

i stated that the network has 3 switches... are these the "segments" you speak about?

thanks

if your talking about groups, there is only one...

Definition: A segment is a specially-configured subset of a larger network. The boundaries of a network segment are established by devices capable of regulating the flow of packets into and out of the segment, including routers, switches, hubs, bridges, or multi-homed gateways (but not simple repeaters).

Network designers create segments to physically separate related computers into groups. This grouping can improve network performance and security. In Ethernet networks, for example, computers send many broadcast packets onto the network, but only other computers on the same segment receive them.

Network segments and subnets serve similar purposes; both create a grouping of computers. The difference between a segment and a subnet is as follows: a segment is a physical network construction, whereas a subnet is simply a higher-level software configuration. In particular, one cannot define a single IP subnet that functions correctly across multiple segments.

So, in your case, you might have all windows xp machines off of one switch, all windows 2000 machines off another, all windows 98 machines off another.

If that were the case, I might be inclined to a bad switch, or perhaps a jabbering nic

If the windows xp and 2000 PCs are all on the same segment or different segments mixed up....btw...you didn't mention what the non-xp machines are....

When the loose connection, do they ALL lose or just some?

[gerryf]

and by connectivity, do you mean a message about network cable is unplugged, or do you mean can no longer surf the web, browse the network?

can you still ping the server from a "disconnected" machine?

[gerryf]

I can't believe I am having a serious networking discussion with someone named poopypants....


I feel....uncomfortable

[poopypants]

NICE - Straight from About.com!!!

anyway, all other machines are 2000

the xp PRO machines are used in all three switches...
so in your definition: 3 segments are being used...

so, no bad switch, no bad nic, and no jabbering...

gerryf: you didn't mention what the non-xp machines are....

Issue: We have XP PRO machines that lose connectivity to:

yes all XP PRO machines (workstations) lose connectivity...

they lose connectivity/ability to print after many different scenarios...
1. if there idle and not in use...
2. if they are in use
3. after about 2-4 hours after initial bootup

[poopypants]

dont worry, you are chatting with a really cool guy!!!

[poopypants]

scenario1: say i have mapped some drives to a windows 2000 box...(from any XP machine)

i double click the mapped icon in My Computer.

Network cannot be accessed...
"\\network\folder\folder is not available..."

[gerryf]

well, I don't feel like typing that crap up when YOU CAN LOOK IT UP YOURSELF!

You didn't answer:

can you still ping the server from a "disconnected" machine?

I am trying to ascertain at what level this is occuring...so far, we have not isolated if it is COMPLETE loss of connectivity or lack of ability to use any network resources, but the underlying hardware is still functioning....but you're right,

so, no bad switch, no bad nic, and no jabbering...

And what I was wondering was if the other machines are win 2000 or even win98....all we had talked about thus far was winxp, so I am not sure what you're quoting me asking what the OTHER machines are and answering windows XP.

So, from a "disconnected machine" can you PING the server using
IP ADDRESS
and/or
hostname
