    Troubleshooting video card issues

    Specs in signature...system is older but has served me well for years. Nothing has changed but over the past few months I've been getting random Nvidia driver crashes, system reboots, and unresponsive black screens. Reset the system back to stock clocks but the issues continued. After trying 5...

    i7 930 heatsink on 970?

    I've built a few VMWare servers for our trade shows around the Lian Li PC-V352B case, Micro-ATX motherboard and i7 930/950 processors. I ordered a 970 this time around not realizing Intel actually uses a decently sized heatsink on this guy, and it wont fit into the Lian Li case. I assume...

    MPLS security

    i've been having some heated debates regarding MPLS security with a few friends... my stance: it's no different from any other FR/ATM transport. VRF separates customer traffic, 2 labels encapsulate/tunnel traffic, and its a private network with private addresses so no risk of public...

    Intel PROSet wireless software deployment

    has anyone deployed the newer versions of the Intel PROSet wireless software via GP? the older ones seemed easier...the admin tool packaged the software and settings into a single file. after doing much scouring i found all the switches for an msi install, but i cant find an msi version of...

    DNS subnet prioritization

    Using Server 2003 R2, is it possible to do DNS subnet prioritization on a classful boundry? I have 3 proxy servers being served round robin from a single A-record. If a client on the same /24 as one of the servers queries DNS, the local proxy is always returned first in the list; great...

    Native VLAN mismatch

    Cisco 2950 connected to multiple Aironet 1231s. The AP's are configured for 2 VLANs trunked back to the 2950. I recently discovered a native VLAN mismatch between the switch and APs, however CDP never complained once. Both are CDP neighbors, logging debugging, but still nothing. Is this...

    Cisco PIX port redirection

    I thought the PIX supported this configuration...tried on 6.3(5), 7.2(3), and 8.0(3) with no luck. Customer has an app running off port 5090. Occasionally, they need to connect to it over port 80 instead. Simple enough I thought... static (DMZ,outside) tcp x.x.x.x 5090 y.y.y.y 5090...

    hybrid vs native mode

    Curious what people's preferences are when it comes to hybrid vs native mode. I dont mind logging into 2 different OSs...in fact I find it easier to make some changes (ie grouping vlan ports) via CatOS. Features like distributed switching arent a factor in my case. However, i read...

    dribble conditions...

    i've been seeing more and more dribble conditions on our core switchports. going by definition: "a dribble condition occurs when the router detects a packet that is slightly larger than specification allows. The router will forward the packet and increment the dribble condition counter."...

    To anyone who does consulting on a large scale for mid-high level enterprise, how do you find it? Pros, cons, things you would do over, things you would never do again, etc. The mere idea of going around the country interacting with new clients, scenarios, problems, resolutions gets my...

    SNMP, how secure?

    How safe are RW SNMP community strings? Are they easily suseptiable to brute-force attacks? Sure a longer string would delay an attacker, but would it just be a matter of time? CiscoWorks requires a RW string to pull/push IOS images, as well as another SNMP command enabling remote reloads...

    VPN performance

    What is the performance difference between 10 users on a Site-to-Site VPN vs 10 users each running a stand alone client on the same network? I would think that the Site-to-Site should exponentially faster. Instead of 10 individual tunnels, everyone would be running under a single tunnel...

    Fast Switching vs Process Switching

    I've researched this topic a good bit and seem to get conflicting answers. CEF uses fast switching, MLPPP uses process switching. On a lower end router (2811), does the balancing advantages of MLPPP outweigh the speed advantages of CEF with equal-cost paths? Trying to use these 2 T1's to...

    Advantages of CSU WICs?

    Besides the obvious space savings, what are the advantages of running a WIC card with a built in CSU over an external unit? All of our old, remote sites still run external CSU's with Serial WIC cards. Verizon provides the CSU and swaps them out if theres ever any problem. If there was an...

    Home theatre PC running a S754 AMD 3200+, MSI FIS2R Neo, 6600GT AGP. Currently has 2x512 PC3200, but I found a Gig stick of 2700 laying around. Would it be worth the added memory to bump the speed down? I know the difference between 1GB and 2GB is negligible, and with the slower speeds...

    Re-connecting to hidden SSIDs with WZC?

    Tested this on a Cisco Aironet 1310 and a 3Com 8760 using multiple pcmcia cards. Access points are running WPA2/AES with PEAP authentication against RADIUS. When using WZC and manually adding an SSID (broadcasts are not allowed), it connects successfull on the first attempt. At this point the...
