May have a flakey switchport or NIC. Have you tried moving your connection to another port on the switch? If switch is full, try swapping ports to see if the problem 'moves'. MCSE CCNA CCDA

If your existing switches are Layer3-capable, then you may not need a router. What mgr/model switches are you using? MCSE CCNA CCDA

I believe what you're asking about is called "split tunnel" "In a VPN context, split tunneling is the term used to describe a multiple-branch networking path. A tunnel is split when some network traffic is sent to the VPN server and other traffic is sent directly to the remote location without...

OK, this is very strange. I have verified what GuestHouse is saying It appears that any email containing the link mentioned that goes between different email systems just disappears. I live in Florida and have nothing to do with Shaw or GoDaddy. I sent emails between all of the following...

That's very strange. I'm surprised you haven't had DC connectivity problems. Proper DNS config is critical to Active Dierctory. Here's the way it should be set up: All internal DNS should point to the server. The server NICs should be configured to point to itself. The only place your ISP DNS...

This is how I normally do it 1. Test new circuit several days before scheduled cut-over. Cut-over scheduled for a Friday at 5:50pm 2. Back up current configs 3. Cut-over circuit & re-config network. Remember, you're going to have new DNS servers. If you have a Windows AD domain you'll need...

The Allied 415s needs routes back to the 172.16.x.x subnets. Add a static route for each subnet pointing back to the corresponding 1841. MCSE CCNA CCDA

Well I've never used VTP, so I can't really miss it. Haven't touched much Cisco recently, but I do know it would make things much easier. I'm building up my lab now to refresh my Cisco skills, need to renew my CCNA. I've got a bunch of older equipment. I'll start a new thread with details. I'd...

Yes, I really do miss the simplicity of EIGRP, but of course that is proprietary to Cisco. So I have to 'make do' with OSPF. As far as reliability, I've only RMA'd 1 in 3 years (I've got about 50 switches), so it seems comparable to Cisco so far. The cost is about 10-20% less than a comparable...

The majority of the cut-overs went well. There've been some minor issues: Had one domain registrar where they wouldn't let me change the DNS records online; had to call them and tell them what I wanted; they said they would make the changes some time in the next 24 hours. Very frustrating. As...

OK, the most recent example I can think of was when we upgraded our internet edge equipment. Datacenter environment: I have multiple high-bandwidth internet lines. One is gig fiber (100Mbps burstable) and a second is 100Mbps copper. I also needed failover and policy-based routing capability...

Yes, I think that's the best way. MCSE CCNA CCDA

FDDI is only 100Mb bandwidth. Assuming your core is capable, you want a full gig for your backbone. Also your 3560G is a gig switch, you'll want to take full advantage of it. Swap positions and put your 3560's on the backbone MCSE CCNA CCDA

The L3 switches I've been using have every router feature I've ever messed with: ACLs, RIP, OSPF, BGP, route-maps, traffic shaping, multicast routing (PIM-SM/SSM/DM, DVMRP), policy-based routing, etc. The biggest difference I see with L3 vs routers is the interface choices. MCSE CCNA CCDA

Until your DNS changes propagate, you probably won't recieve much email. The majority of email servers will queue the mail and resend several times before outright bouncing it. How long it take before it gives up and bounces the email is dependent on how the server is configured. I've seen as...

Burt, I agree for the majority of L3 switches. But I've been using Extreme equipment for the last few years and their L3 switches have all router capabilities. Maybe because Extreme doesn't make routers? [pipe] MCSE CCNA CCDA

A few other things to think about... While you're modifying your DNS, don't forget the MX records as well as any SenderID/SPF records. Check all your remote access (VPN, RDP, VNC, etc.) If you are using Exchange 2007, you may have to mess with your digital certificates. If you use...

??? What IP? What gateway? You gotta give me something to work with. Need specifics. Post a sanitized config. MCSE CCNA CCDA

Not a lot of information here...? Note that a device's default gateway must be on the same subnet. MCSE CCNA CCDA

If you have any control over scheduling the cut-over, try to do it late on a Friday. This gives you time to troubleshoot any issues. It also gives you the weekend for DNS to propagate so everything is done by Monday morning. MCSE CCNA CCDA
