If a character likes to use long-duration buff spells, perhaps even has some Permanency'd spells on herself, are there ways to protect these effects against unwelcome Dispel Magic and similar?

If the character uses a Ring of Counterspells and puts (Greater) Dispel Magic in it:
-Does that protect against area dispel magic?
-Dispel Magic can counter many other spells. Does this apply to a DM put into a ring of counterspells? If so, does this mean the DM will try to counterspell the first spell of any kind cast agaisnt the wearer of the ring, or that they get to choose?
-When Dispel Magic is used to counterspell other spells, the counterspeller needs to make a caster level check to do so successfully. Does this apply when DM is used to counter another DM?

Cast them with as many CL boosters as possible?

Aside from the Ring of Counterspells, there's Spell Turning and boosting caster level. The Ring of Enduring Arcana is particularly good for this if you have a large number of buffs.

-Does that protect against area dispel magic?
Yes, provided it is the correct version of the spell. If the ring has Dispel Magic, it will not protect against Greater Dispel Magic. If the ring has Greater Dispel Magic, it will not protect against Dispel Magic.

-Dispel Magic can counter many other spells. Does this apply to a DM put into a ring of counterspells? If so, does this mean the DM will try to counterspell the first spell of any kind cast agaisnt the wearer of the ring, or that they get to choose?
The ring specifically only counterspells the exact spell that is put in it. The extra counterspell capability of Dispel Magic is ignored by the item. You do not get to choose, the ring does its counter automatically. Even if you don't even know a spell is being cast at all, if it's the right spell and you're targeted or in the area, it will counter it.

-When Dispel Magic is used to counterspell other spells, the counterspeller needs to make a caster level check to do so successfully. Does this apply when DM is used to counter another DM?
No. In the case of DM vs DM, the normal counterspell mechanics can be used because they are the same spell. Dispel Magic's specific counterspell option only matters when you're casting it normally rather than as a "true" counterspell.

Nothing. Spell Immunity (http://www.d20srd.org/srd/spells/spellImmunity.htm) only works against spells that allow SR. Dispel Magic (http://www.d20srd.org/srd/spells/dispelmagic.htm) doesn't allow SR. Even if it did work, there's more than one way to dispel a cat so that would only be part of a good defense.

Check out Spellblades from... some forgotten realms book. They are just plain rude versus targeted spells.

Ring of Enduring Arcana (Complete Mage) is a huge help for 6000gp

I think there's a spell called Dispelling Buffer or something that helps prevent your spells from being dispelled. SpC, maybe?

Boost your normal CL as much as possible and get extra effects that make it harder to dispel your spells from feats and prestige classes. Fill a Ring of Greater Counterspells with a Greater Dispel Magic, buy a Ring of Spell Battle to redirect one spell per day, and cast Duelward so you can make an immediate counterspell as a last resort. This gives you three options for stopping targeted dispels, the most dangerous. At the start of the day, boost your CL to 1 higher than the CL you'll be using for all your important buff spells and cast a bunch of low level long duration spells like Mage Armor or Low Light Vision. These dummy spells will be checked first for area dispels since they have a higher CL than your actual buffs and will give the area dispel multiple chances to hit a single dummy spell instead of your real buffs.

I don't know where the "dispelling buffer" spell was, but now that I think about it I wouldn't be surprised if it was a Faerun book and for some reason I think it might have been cleric only. It was pretty good though, I know that much.

Spellblades are in Player's Guide to Faerun, and are indeed crazy, the only trick is that you have to be wielding the weapon for the ability to work. They make you immune to a single targeted spell and let you reflect it as a free action on your turn, and are cheap. Really cheap. As in, candy to anyone over 10th level cheap. A Spellblade against Greater Dispel Magic would be an incredible investment for anyone fighting just about anything. Lots of outsiders and other high level creatures can Greater Dispel at will, and even if there are other dispels (like Chain Dispel and Reaving Dispel, both of which are are higher level investments), that's what your Duelward and Ring of Spell Battle are for. If you're mean, you could try carrying small double weapons or putting the enhancement on shields, armor spikes, and spiked gauntlets to have multiple Spellblade defenses active. Really, it's just a ridiculous ability. Faerun likes their broken items.

It's a psionic power, actually, and it's in the SRD (http://www.d20srd.org/srd/psionic/powers/dispellingBuffer.htm).

Depends on how much your DM plooks around on dispells. If all you need to worry about is Dispel Magic / Greater Dispel Magic, then yeah, a Ring of Counterspells (Greater Dispel Magic) for when you're targeted directly. For when you're not targetted directly:

For Area dispels:
Cast most things at -1 caster level. Coat yourself in Arcane Marks at full caster level. Area Dispels discharge on the first thing they dispel successfully for a given target, and they start with the spells of highest caster level. So if you have 60 Arcane Marks on yourself, you're not liable to have anything else dispelled (and, as they last a month on living critters, that's just two cantrip castings a day).

If, however, your DM makes use of Dispelling Screens and such, you'll want a bit more protection:

Some casters have access to Use Magic Device (one of the better reasons to take Loremaster), and thus can make sue of such things as the Bead of Karma from a Strand of Prayer Beads. Combine with the Ring of Enduring Arcana, and your caster level is 8 higher than your character level. Combine with an Orange Prism Ioun Stone, and it's 9 higher. Levels in Archmage can make that ten or more higher. This type of caster level stacking will stop basically anything short of Disjunction or "No, you lose" semi-arbitrary effects.

My suggestion is don't. Whatever workaround you use, your DM can beat, because the DM is god. Building an impregnable Maginot Line (http://en.wikipedia.org/wiki/Maginot_Line) is an invitation to go through Belgium.

If he feels like Dispelling your buffs, let him. They won't always succeed, and you have plenty of other magical tactics you can use - Summon spam, No Save magic, Scry and Die, etc.
