Hi, Berrystraw, and welcome to A2k.
Appservices is a component of Iomega software, so its unsurprising it would appear to be associated with problems involving Iomega drives. I'm not sure thats all the problem you've got, but its a relatively easy one to deal with, so lets start with it. First, go to Device manager (Start>Administrative Tools>Computer Management>Device Manager or right click the "My Computer icon either on your desktop or start menu, select "Properties", Select the "Hardware" tab, then click "Device Manager". Locate your Iomega drive, highlight it, right-click and and select "Properties", select the "Driver" tab, then select-and confirm "Uninstall" and click "OK". Return to, or relocate, the highlighted Iomega drive entry in Device Manager if its still there, make sure its highlighted, right-click on it and select-and confirm "Uninstall". Shut down your machine - shut it down, don't just restart it. When it has powered down, physically disconnect the Iomega drive from your machine, let the machine remain shut down for at least a full minute, then reboot.
When your machine has rebooted, go to Start>Control Panel>Add/Remove Programs, locate and uninstall any Iomega software if you find any there, then, using Windows Explorer (Windows key + E or right-click the "My Computer" icon either on your desktop or start menu and select "Explore"), look for and delete any folders named Iomega or clearly related to Iomega or applications you know to be part of the software you originally installed with your Iomega device. When you've eliminated all you can find, reboot.
At that point, connect to the internet, go to
IOMEGA Support and Downloads, locate and download the latest drivers and software for your particular Iomega product and your particular operating system - you might also want to download the product manual, to get the installation details, if you no longer have your manual, and follow whatever installation proceedure as may be recommended for that product, using the downloaded drivers and software when and as prompted by the install routine. Second-best would be to use the install disk that came with your device, if you still have it, just repeating the original install routine. It would still be a good idea to get and install the latest, currently updated drivers and software, if any later than those that came with your device are available.
As for Internet Explorer problems specifically, the first step ought to be to go to
Windows Update, see if you need any Service Packs, Critical Updates, other patches, software or driver updates, and if so apply them.
A handy 3rd-party software fix that often corrects a number of IE issues may be found
HERE
If that didn't help, try going to Start>Control Panel>Add/Remove Programs, and see if Internet Explorer is listed there (if not, we can work around that, but lets not go there unless we have to). If so, select it and select "Repair". You may be prompted for your original XP install disk, so have it (or any other Win XP install disk - though a vendor's "Restore" disk probably won't work without a bunch of fiddling around) handy, and follow the prompts. Microsoft offers an article on installing/repairing IE in Win XP
HERE, and another good set of tips may be found
HERE.
Alternately, you can download IE6 (though to install it you'll most likely have to do some more fiddling around - which I'll be glad to step you through if it comes to that, but lets hope it doesn't come to that)
HERE - but beware, its a huge download, some fairly geeky Windows tricking likely will be required to get it to install, and it will still need considerable updating once installed. Both it and Service Pack 2 may be ordered from Microsoft at no charge (though a small shipping fee may be applied) if you'd rather not download them.
Other than for Microsoft sites, such as Windows Update, which require Internet Explorer, you might find yourself well served by an alternate browser, such as
FireFox.
Hope that helped some - lemme know if you need more, and I'll see if there's anything else I can offer. just come back to this thread and click "Reply".
Good luck.
