For CCENT/CCNA you do not need to buy hardware at all. Save yourself $ by mastering GNS3. Spend $ on good books or CBT's. bio

Well we had 3com 5500EI's in the past. Back then the ip forward-broadcast command did never work in VLAN mode. perhaps there is newer firmware available now. I would check at the HP site (if you have support contract) bio..

As you might know the 4500 series have a maximum of 10 slots. If you need more then you'll need the 6500 series. We have 2 cisco 4506 that handle our core traffic. Untill now they can handle traffic with ease. So a 6500 series might be a little overkill for a school environment. But i don't know you're infrastructure. We handle about 3000 wireless devices and 1000 pc's with those 2 cores. regards bio..

Allways go for the Cleanair technology in an school environment if you have the budget. Running 180 x 3502 APS with cleanair in our school. The ablility to detect RF interference and adjust your WLAN automatically is just great. Remember all those microwaves, camera's and alarm detection crap regards bio..

Open an MMC session and add the certificates snapin. Choose Local computer. Browse to the personal - certificates store. Rightmouseclick on all tasks - import. Here you can select your CRT file. regards bio..

Place all GPO modifications in a REG file. use this REg file on the PC's. But hey.. if you are an admin then you are able to create a small AD infrastructure regards bio

probably show lldp since CDP is cisco proprietary. regards bio..

Cisco 4506E's over here. 2 x 10 GB link between them. VERY happy with them (running 6 months solid now. (before we had 3com 5500Gs). bio..

Just create an RDP publishing rule.. like here. regards bio

+1 for cisco with cleanair bio..

Can you give a little more detail about your setup ? network relationships etc.. bio..

Exchange 2010 with TMG - OWA Expired Password issue regards bio..

Invest time and effort at this moment. Your network will get bigger and bigger. I would reconfigure this network. Create separate VLAN's for Wireless, Servers, Workstations, printers. Thus creating /24 or /23 networks. So it will be easier to do it now then in the future. regards bio..

To start off I would make sure that that website is not cached on the TMG box.

You can do this on an IP basis. So assign static IP those computers or an DHCP reservation. Or a special VLAN for these computers.. then create a rule with these IP (computers) with a blocklist assigned. place this rule above your normal rules. bio..

The next thing i would do is to look for packetloss on your internet pipe. You ISP can give you this information or if you have a decent router then you can check that info on the interface that connects to your ISP. bio..

XP or windows 7 clients ? bio..

A visit to the netherlands is also possible

The "incorrect header checksum" problem can be solved by disabling ALL ip offload capabilities on your NIC (the machine you use for sniffing). regards bio..

Do you have SP2 installed and SP2RU1 ? I dunno for sure if SP2 deletes the created registry settings required to properly install SP1RU2. Also don't know if they are still necesary. bio..

VMware has a solution for this : VM Fault Tolerance bio..

I wrote an article a while ago.. it might help others. bio..

What kind of reporting details are you looking for ? bio..

I don't know if you have a contract (SLA) with the internet pipe owners ? perhaps packetloss ? let them do some measurements ? maybe fire up wireshark on several locations ? just some idea's here bio..

Well... if administrator is the owner then it could be that administrator has posted it (or someone who knows the pass)...or you have a backup solution that edits this information. Then you should change this asap. I think you have no other alternatives to find this culprit. You could also look into file object auditing. bio..
