The network location cannot be reached

Jason Tramer Jason Tramer Profile: Jason Tramer

I was working with an issue with an old file windows 2000 file server where some users were able to access network shares alright but some couldn’t. The ones that couldn’t could ping it ok but when trying to access file shares would get the error “The network location cannot be reached”.

After doing a quick google search on the error I discovered that this was normally at Netbios error and i followed the steps listed in various articles.

Restart the Computer Browser service

Disable the Routing and Remote access service

Ensure Netbios over TCP/IP is enabled

etc..

None of these fixed the issue. After checking the event log however I found the issue, there was another computer on the network with a duplicate name!

After removing the duplicate name computer from the network everything worked fine.

RIM announces free version of BES

Jason Tramer Jason Tramer Profile: Jason Tramer

In an effort to no doubt drive business RIM has announced they are releasing a free version of BES, BES Express.

In addition from what I have heard BESX can run on your Exchange server and does not need a separate server of its own, which makes it a very affordable solution for the SMB market.

This is great news for consulting companies such as the one I work for where in a lot of our  small-medium business’s we support would be very interested in having a BES server but can’t afford the costs.

Cisco router not handing out DNS server to DHCP clients

Jason Tramer Jason Tramer Profile: Jason Tramer

I had a weird issue yesterday. I had a Cisco 1800 series router that was configured to hand out DHCP and up until a few days ago everything worked fine with it. Then suddenly out of the blue it still handed out DHCP but did not hand out the DNS-Server option even though it was configured.

I tried removing and re-adding that option and even rebooting the router but that didn’t resolve the issue. In the end I blew away the entire DHCP pool and re-created it and that resolved the issue.

Strange though.

Installing an XP vm in ESX

Jason Tramer Jason Tramer Profile: Jason Tramer

Unfortuneatly XP lacks the drivers for either the LSI or Buslogic controllers that ESX uses for their virtual harddisks.

Here is a good article on this that includes links for the controllers:

A Decade of Technology

Jason Tramer Jason Tramer Profile: Jason Tramer

For my last blog post of the decade I wanted to take a step back and look at how technology has changed in the last ten years. It’s pretty stunning when you think about it. Being a consultant and thus always being the vanguard for new technology it sometimes shocks me when I wax nostalgic and think back to where we were.

So ten years ago this day where were we with technology? Well Cobol programmers were getting rich and doomsday prophets were proclaiming the apocalypse was nigh or don’t you remember the Y2K scare?

Here is my top five list of technology which has really come into it’s own in the last decade. Some of these technologies existed in some form before but I think it’s really in the last ten years that they have come into their own

5. Google

Do you remember when geeks would argue about which search engine is the best? Well that pretty much came to a halt with the advent of Google. You only have to walk by a bunch of ditzy blonde airheads using Google as a verb to realize how big this has become.  Google made the web far easier and far friendlier place which in turn spurred a lot of the other advancements in the web.

4. Cellular phones/Palm computing

Ten years ago these were separate concepts. Cell phones were big and bulky, palm computers were slow and crappy. Now you have Blackberries and iPhones, great technologies which ensure that I can be harrassed by work and drunken friends at all times of day and night in so many different ways.

3. High Speed Internet

Do you remember modem’s? Do you recall how much they sucked? This one should really be rated higher because so much of our technological advancements would never have happend without high speed internet.

2 Linux/Open Source

Sure Linux has been around since 1991, but the last ten years has seen it surge in popularity. So many systems and technologies out there are now being developed and running on a linux kernel. It’s everywhere and you probably don’t even know it.

1 Virtualization

The old paradigm is broken. Server virtualization has changed everything about being a sysadmin.  The idea of installing a server OS directly onto a box without a hypervisor is mostly ludicrous. There are some exceptions where this is still necessary but look for even these to go away in the future.

So what is my prediction for the next decade.

IP v6 – This will change everything all over again.

VOIP – I was originally going to include this above and then I realized that as far as VOIP has come this market is so hugely still untapped. It will be this coming decade and not this past one where VOIP makes its mark.

Desktop Virtualization – Thirty years later and we are now going back to thin terminals!

Have a happy new year!

Allowing management access to an ASA across a site to site VPN tunnel

Jason Tramer Jason Tramer Profile: Jason Tramer

Ok, so you want to manage your ASA from a network connected via site to site VPN tunnel. No prob. Two easy steps makes this happens.

First you have to add the network as an allowed access via the inside network. (I will use the 192.168.1.0/24 network in my example)

From CLI it’s:
http 192.168.1.0 255.255.255.0 inside

If this was a directly connected network then that is all you would have to do, however since it is connected from VPN you also need to specify the inside interface as a management interface with this command.

management-access inside

You can do all this from the ASDM as well:

Under Configuration, Device Management, Management Access:

Add the network on the inside interface  in the ASDM/HTTPS/Telnet/SSH section

Then enable management access on the inside network under the  Management Interface section

Microsoft refutes IIS “semi-colon” bug

Jason Tramer Jason Tramer Profile: Jason Tramer

A few days ago I posted about a newly discovered bug in IIS 6.0, well Microsoft has refuted that this represents a security risk. Read about it here;

http://www.theregister.co.uk/2009/12/30/iis_web_server_bug_rebuttal/

Hmmm who to believer? Security experts or Microsoft? Tough call there.

No really it’s not a bug it’s just a undocumented feature, right …..

This is usually the point where I make a snarky, sarcastic commment about Microsoft but really it’s just too easy.

Citrix Client being released for the Blackberry

Check it out:

All I can say is it’s about time. This has been available for the iPhone for quite awhile now. Given that Blackberry tries to position itself for the enterprise workspace you would think this would have been available for awhile now. Yeesh.
